PREFACE

Ten years ago aviculture had hardly been thought of as a school subject. To-day it is taught in thousands of schools, and in some states instruction in poultry culture is required by law. This rapid change in sentiment and situation has resulted from a combination of causes. When agricultural colleges established poultry departments, it was found that a large part of those applying for admission to them had neither the practical knowledge of poultry nor the general education that they needed to do work of college grade. About this time also the interest in nature study began to take a more practical turn, and attention was directed to the superiority of domesticated to wild animals and plants as material for school studies of the phenomena of physical life. Added to these special causes was a general cause more potent than either: great numbers of people had reached the stage of experience in various lines of aviculture where they realized keenly that a little sound instruction in the subject in youth would have been of great value to them later in life, saving them from costly mistakes. To these people it seemed both natural and necessary that the schools should teach poultry and pigeon culture.

Developing as the result of such a combination of causes, the demand for an elementary textbook on poultry came with equal force from country schools, where poultry might be kept on the school grounds as well as by every pupil at home, from city schools, in which all instruction must be by book, and from all types of schools and conditions of life between. Had there been only the extreme classes of schools to consider, the natural way to supply the demand would be with a special book for each distinct type of school. The idea of one book for all schools, from which each might use what seemed to suit its requirements, was dismissed as impractical while so large a proportion of teachers were but slightly acquainted with the subject. It is believed that the plan of making an elementary reading course for general use, and a secondary book of a more technical character for use where practice courses are given, is the best solution of the problem under existing conditions.

In this first book the object is to tell in plain language the things that every one ought to know about poultry, pigeons, and cage birds; to teach fundamental facts in such a way that they will be fixed in the mind; to excite interest in the subject where none existed; and to direct enthusiasm along right lines. While the demand has been almost wholly for a poultry book, pigeons and cage birds are included, because they are of more interest than some kinds of poultry and better adapted than any other kind to the conditions of city life.

In regard to the time that should be given to this course, one period a week for forty weeks is better than a period a day for forty days, because the average person, young or old, retains a great deal more of what is read or heard about a diversified subject if the ground is covered by easy stages with comparatively long intervals between. References for collateral readings and suggestions for original investigations are omitted, because, in the author's opinion, what work of this kind it is desirable for a high-school pupil to do should be done by those taking practice work in the advanced course.

OUR DOMESTIC BIRDS


CHAPTER I
BIRDS AND THEIR RELATIONS TO MAN

Definition of a bird. A bird is a feathered animal. The covering of feathers is the only character common to all birds and not possessed by any other creature. The other characters—the bill, the wings, egg-laying, etc.—by which we usually distinguish birds from animals of other kinds are not exclusive bird characters. Turtles have beaks, and there is one species of mammal (the ornithorhynchus) which has a bill like that of a duck. Many insects and one species of mammal (the bat) fly. Insects, fishes, and reptiles lay eggs, and there are several rare species of mammals that lay eggs and incubate them. On the other hand, some birds are deficient in one or more of the typical bird characters. The ostrich cannot fly. The penguin can neither fly nor run, and cannot even walk well. The cuckoo lays its eggs in the nests of other birds, leaving to them the hatching and rearing of its young. These exceptional cases are very interesting because they show that animals now quite different in structure and habits had a common origin, but in no case is there such a combination of characters that any doubt arises whether the creature is a bird or a mammal. The characters which typically belong to birds attain their highest development in them, and in most cases this is due to peculiar adaptabilities of the feathers.

The Anglo-Saxons' name for a bird was fugol (the flying animal). The young feathered creature they called bridd (the thing brooded). This name was also sometimes given to young mammals, but it applied especially to the young of feathered creatures which were more dependent upon the parent for warmth than others. Our English words "fowl" and "bird" come from these Anglo-Saxon terms. At first "fowl" was applied to large birds and "bird" to small ones, but gradually the use of the name "fowl" was limited to the common domestic fowl, and "bird" became the generic name for all feathered creatures.

Place of birds in the animal kingdom. Zoölogists rank mammals higher than birds because man is a mammal and his general superiority to other creatures determines the rank of the class to which he belongs. Yet, while placing birds below mammals in a simple classification of animals, naturalists point out that birds are the most distinct class in the animal kingdom. If we compare birds and the lower mammals, and compare the relations of each class to man, we see at once that nothing else could take the place of birds either in nature or in civilization. Among birds are found the highest developments of animal locomotion and of the natural voice, capacity for language far beyond that of other creatures (except man), and family and community relations resembling those of the human race. Hitherto in the history of the world mammals have been more useful to man than birds, but birds have given him some of his best ideas, and with the advance of civilization the lower mammals become less necessary and birds more necessary to him.

Flight of birds. It has been said that "on the earth and on the sea man has attained to powers of locomotion with which, in strength, endurance, and velocity, no animal movement can compare. But the air is an element on which he cannot travel, an ocean which he cannot navigate. The birds of heaven are still his envy, and on the paths they tread he cannot follow."

Since that was written practical flying machines have been invented, but in these, as in boats and ships, man has merely devised a machine which under his control can do laboriously and at great risk what the bird does naturally and easily. To birds man is indebted for his first lessons in navigating the water as well as for his ideas about airships.

Voices of birds. With few exceptions the different kinds of animals have natural languages through which individuals of the same species can to some extent hold communication with each other, and which are partly intelligible to other creatures. In all mammals except man, and in most birds, the range of expression is very limited and the sound of the voice is disagreeable; but a great many species of birds have very pleasing notes, many have very beautiful natural songs, and some readily learn the songs of other species. Man learned melody from the song birds. There are also many species of birds that can imitate a great variety of sounds, and even learn to speak words and short sentences. Birds that learn to talk often show intelligence in their use of words. This is the more remarkable because the intelligence of birds is not of a high order, but is distinctly inferior to that of the common domesticated mammals.

Social relations of birds. In aërial birds (except the cuckoos) the male and female pair, build a nest, and both take part in the incubation of the eggs and the feeding of the young. Usually a pair once mated remain mated for life and are very devoted to each other. In wild land birds the pairing habit is not of advantage to a species, but still the tendency to single matings is very strong. When land and water birds are domesticated man tries to break them of this habit because the males produce no eggs and he prefers to eat them while they are young and their flesh is tender. But, as will appear in detail when the different species of birds of this class are described, he does not always succeed in doing this. Even the domestic fowl and duck, in which pairing has been prevented for centuries, often show a strong tendency to pair; and the females with broods of young usually separate from the flock until the little ones no longer need their care. With this separate family life there is still in most species of birds concerted action by communities in migrations, in forming colonies, in attacks on other creatures, and in defense from enemies. From the earliest times of which we have knowledge the devotion of birds to their mates and to their young has afforded the most common and most beautiful illustration of family life in nature.

Place of birds in domestication. The place of birds among domestic animals corresponds to that of garden vegetables, small fruits, and flowers among cultivated plants. The great staple agricultural crops—corn, wheat, oats, barley, hay, apples, oranges, horses, cattle, sheep, hogs, etc.—are produced mostly by men who make farming and stock-growing their business. But, while large quantities of garden vegetables, small fruits, flowers, poultry, pigeons, etc. are grown by people who specialize in them, the greater part of the supply in all lands comes from small gardens and small flocks on ordinary farms and in the back yards of town homes.

Uses of birds in domestication. With the exception of the cage birds and the ostrich, all our domestic birds are valuable for their flesh; but, as some kinds can be produced more easily and cheaply than others, people growing birds for the table give most attention to those that can be grown most profitably, and the others are grown principally by those who prize them for rarity, beauty, or some peculiar quality.

The eggs of all birds are edible, but birds differ greatly in the number of eggs that they lay and in the disposition to lay them in places provided for the purpose. So, nearly all who keep birds for their eggs keep fowls, which are the most prolific and most docile, and hens' eggs are the staple eggs in the markets.

The feathers of birds are used for pillows and beds, for feather dusters, and in various ways for ornament. Except in the case of the ostrich, however, the value of the feathers of domesticated birds is so small that no one grows birds primarily for their feathers. On the other hand, those who keep birds for pleasure find their greatest enjoyment in breeding them with colors and markings difficult to produce. Choice specimens of fancy-bred birds bring prices many times greater than the value of their flesh and eggs for food and of their feathers for use or ornament. Fancy feathers have no more value than others except on the living birds.

While those who keep birds for pleasure nowadays give most attention to breeding fancy stock for exhibition, several kinds of pigeons are kept to entertain by their flying performances; and—outside of the limited class of those who breed them especially for exhibition—canaries are valued according to ability to sing. The brutal sport of cockfighting was a popular pastime with our ancestors until prohibited by law, and is still prevalent in many lands. In early times birds of prey were captured when very young and carefully trained to hunt for their masters. Under the feudal system there were regulations prescribing the kinds of birds which different classes of men might use in this way: the eagle and vulture were for emperors only; the gyrfalcon for kings; the lesser falcons for nobles; the harrier for esquires; the merlin for ladies; the goshawk for yeomen; the kestrel for servants; the sparrow hawk for priests.

Much of the value of various kinds of poultry comes from their ability to destroy insects which damage vegetation, and to maintain themselves on these and on foods not available for the larger domestic mammals. The services of poultry in this respect being limited to those insects that can be secured from the ground, and to areas on which the birds can live safely and do no damage to crops, we are dependent upon wild aërial birds to keep insect life in check on trees and high bushes and on land not occupied by poultry.

Place of wild birds in civilization. As no insect-eating aërial birds have been domesticated, the preservation of wild birds that destroy insects is of as much importance to man as the production of domestic birds. Indeed, the wild birds are much more valuable to us in the wild state than they would be if domesticated.

In nature species prey upon each other—the lowest forms of life upon inorganic and decayed matter, the higher forms upon the lower, the larger creatures upon the smaller, the savage upon the defenseless. Fertile lands not only produce luxuriant vegetation but teem with insect life, which, if not kept in check, would soon destroy that vegetation. In tropical and semitropical regions there are mammals, some of them quite large, which feed upon insects. In temperate regions where insects are not to be obtained during the winter, there would be no adequate check upon their increase and the consequent destruction of vegetation if it were not for the vast numbers of insect-eating migratory birds which come to these regions for the summer. Necessary as these birds are to vegetation on uncultivated lands, they are more necessary in cultivated fields, orchards, and gardens where the crops are more attractive to insects than the mixed vegetation on wild lands. As insect destroyers the domestic birds that are kept on cultivated lands only fill the place of the nonmigratory wild birds that have been driven away or exterminated. So it is to the interest of every one to protect insect-eating wild birds, for although these birds may do some damage to crops, their service usually more than pays for it.

Classes of domestic birds. There are three classes of domestic birds—poultry, pigeons, and cage birds. The poultry class comprises land and water birds and contains nine kinds—fowls, ducks, geese, turkeys, guineas, peafowls, pheasants, swans, and ostriches. The pigeon class has but one kind, the pigeon, which is the only aërial bird domesticated for economic purposes. The cage-bird class has as its most important representative the canary. The other birds of this class have never been popular in America.

The question of increasing the number of species of birds in domestication interests many people. There is a general impression among those not familiar with the commercial aspect of aviculture that many more species might be domesticated. While it is true that many birds capable of domestication have not been domesticated, there are few of these that would serve any purpose not better served by some species already domesticated. It will be shown as the different kinds and varieties of domestic birds are discussed that the most useful kinds are always the most popular, and that many others are kept principally as ornaments. The number of ornamental creatures that can be kept in domestication is limited, for as a rule animals, like people, must earn their living.


CHAPTER II
CHARACTERS AND HABITS OF BIRDS RELATED TO USE

Feathers. The feathers of a bird are the most highly developed form of protective covering in animals, serving other important functions in addition to the primary one. Compared with the hair of a mammal or the scale of a fish or of a reptile, a typical soft feather from the body of a bird is a very complex structure, partaking of the characters of both scales and hair. The fact that birds have scales and hair as well as feathers shows their relation to these other forms of animal covering. This is best observed on a fowl. The legs of a fowl are normally smooth, with scales on the front of the shank and on the upper surfaces of the toes. In feather-legged fowls the feathers appear first along the outer sides of the shanks and toes. As the number of feathers is increased they grow longer and more feathers appear, until in the most heavily feathered specimens the soft skin is covered and the scales are almost hidden.

The face of a fowl is normally almost bare, the skin being a bright red like the comb and wattles; but at a distance of a few feet we can usually see some very small, fine feathers on it, and if we examine closely we see in addition still finer growths—hairs. Among the body feathers of a fowl, too, are quite long hairs. These are most easily observed after a bird is plucked. They do not come out with the feathers, and are removed by singeing.

Structure of feathers. The smallest feather that to the naked eye appears as something more complex than a hair, looks like a little bunch of fuzzy filaments. This is called down.

In the next higher form of feather a small round quill appears with filaments protruding from it like the hairs in an artist's brush. Such a feather is called a stub feather, or simply a stub. The best place to find these is on the outside of the shank of a fowl with scantily feathered legs.

The first form of the complete feather is best observed either on the head of a fowl or at the hock joint. The feathers in these places are very small, yet complete. The round quill is lengthened into a shaft. Extending from each side of this shaft is a single row of filaments, called barbs, the edges of which, interlocked with little hooks, form the web of the feather. On other parts of the body of the bird the feathers are larger, but the general structure is always the same. The size and special structure of the feather are always adjusted to suit the part on which it grows or the service which it has to perform.

As the first function of the feathers is to keep the bird dry and warm, the body feathers are all soft as compared with the large stiff feathers of the wings and tail; yet as we look at the feathers on different parts of the body of a bird we notice differences in their structure, and also notice that the structure of a feather is not always the same throughout its length. On the exposed parts of the feathers of the neck, back, wings, and breast the web is perfect and the feathers overlap so closely that they present a smooth surface. Under the surface, especially next the skin, the barbs are not smoothly joined, but are fluffy. Thus the same feathers which present a hard, smooth surface to the weather provide a soft, warm garment next the skin. Under the wings and on the underside of the body the feathers are quite fluffy throughout their whole length.

Arrangement of the feathers. As you look at a living bird the feathers appear to grow on all parts of the body. When the feathers are removed from the bird you see that while the skin is nearly all rough, with the little elevations where the feathers were removed, there are quite large areas where the skin is perfectly smooth, showing that no feathers grew there. These places are bare because feathers on them would interfere with the movements of the bird. The feathers on adjacent parts give the smooth areas sufficient protection.

Decorative feather forms. The natural decorative forms of plumage are found mostly in male birds and consist of extraordinary developments of the plumage of the neck and back, where the male birds of some species always have feathers differing in form from the feathers on the same parts of the female. When a feather appendage not common to a species is developed on some varieties, as the crest and beard on fowls and the ruff on pigeons, both sexes have it. The most interesting feather decorations will be described particularly in the chapters on the species on which they occur.

Fig. 1. Brown Leghorn chick (one day old)

Color in feathers. While colors in the plumage are distributed very differently in different species of birds, often making combinations peculiar to a species, there is in all the same wonderful formation of patterns, that depends for its effect in a section upon some overlapping feathers being marked alike and others having a different marking; and for the effect in a single feather, upon adjacent barbs being now alike, now different, in the distribution of the pigment in them. The best common example of a pattern covering a series of feathers is found on the wing of a Mallard Duck or of a Rouen Duck. Interesting examples of the formation of patterns on a single feather may be found in the plumage of barred, laced, and penciled fowls, and also in the lacings on the body feathers of the females of the varieties of ducks mentioned. Perhaps the most interesting illustrations of this kind, however, are to be seen on the plain feathers of the guinea and the gorgeous tail of the peacock.

The pigment which colors the plumage may be found in soluble form in the quills of immature colored feathers. It is not conspicuous unless it is quite dark. In black fowls it is often so abundant that a part remains in the skin when the feathers are removed. After the pigment is deposited in the web of the feather the color is fast. Water does not affect it, but it fades a little with age and exposure. New plumage usually contains a great deal of oil, a condition which is most conspicuous in white birds, to whose plumage the oil gives a creamy tint. In colored birds the presence of a large amount of oil in feathers is desirable because it gives greater brilliance to the plumage.

Growth and molting of feathers. The first covering of a young bird is down. The young of birds which nest on the ground have the down covering when hatched; others acquire it in a few days. In small land birds which feather quickly, as Leghorn and Hamburg chicks, the largest wing feathers may have started to grow before the chick leaves the egg. In most kinds of poultry, however, the young show no signs of feathers for some days. The down is gradually replaced by small feathers, and these by larger feathers as the bird grows. As feathers in all stages of growth are found on the young bird at the same time, it is not known whether all feathers are molted the same number of times. In cases where some feathers were marked and watched, or where the colors changed with the changing feathers, it appeared that after the down three sets of feathers were grown in succession, the third and last making the adult plumage of the bird. This coat remains until the following summer or fall, when it is molted and replaced by a new one.

Flight. The habit of flying is objectionable in domestic birds because it makes them more difficult to control. It has no direct use except in pigeons kept for flying. There is, however, a very important connection between development for flying and the value of birds for the table. The muscles of the wings furnish the greater part of the edible meat of most birds. The most desirable birds for food purposes are those which have the wing muscles well developed, yet not quite strong enough to enable them to fly easily. In such birds the breast meat remains comparatively soft through life, while in birds that fly well it becomes hard in a very short time. That is why the breast meat of the pigeon is relatively tougher in an old bird than the breast meat of a fowl or turkey.

The balance between capacity for flight and neglect to use it, which is desired in birds grown for the table, is secured by giving them opportunity to exercise their wings moderately but not for progressive practice in flying, which would soon enable them to fly easily over the fences used to confine them. To regulate such exercise the perches for birds that roost are made low, or in an ascending series in which each perch after the first is reached from the one below it, while fences are made so much higher than the distance the bird is accustomed to fly that the failures of its first efforts to go over them discourage it. Ducks and geese, which do not roost, flap their wings a great deal, and if they have room often exercise them by half running and half flying along the ground.

Mechanism of the wing. In its structure and in the muscular power that moves it, the wing of a bird is a wonderful piece of mechanism. A bird in flying strikes the air with its wings so rapidly that the movements cannot be accurately counted. The heron, which is a slow-flying bird, makes from one hundred twenty to one hundred fifty downward strokes of its wings a minute. As each downward stroke must be preceded by an upward stroke, this means that the wings make from two hundred forty to three hundred separate movements a minute. In such swift-flying birds as the pigeon the movements of the wings can be distinguished but cannot be counted. The fastest movements of the wings are not made by the swiftest fliers. In order to fly at all some land birds with comparatively small wings have to move them so fast that the movements make a blur and a whirring noise. The partridge is an illustration of a bird of this class.

If the supporting surface of the wing of a bird were made of skin, like the web of the foot of a swimming bird, it would be necessary to fold the wing for each upward stroke. It is here that the structure of feathers adapts itself to the rapid action required for movement in the air. The wing is not one surface but a series of narrow surfaces lapping in such a manner that they unite to form one broad surface when the downward stroke is made, and with the upward stroke are separated so that the air passes between them. Greater power in the downward stroke and less resistance in the upward stroke are also secured by the curvature of the wing. The under side is concave, the upper side convex. Thus in the downward stroke the wing gathers the air under it and so increases the pressure, while in the upward stroke it scatters the air and reduces the pressure.

If the wing were equally rigid throughout, the movement of the bird would be mostly upward. The bird in flying moves forward because the front of the wing is rigid and the tips of the feathers, which are directed backward, are flexible. So the air compressed by the wing in the downward stroke escapes backward, and in doing so propels the bird forward. The principle is the same that is applied in the screw propeller of a boat or an airship, except that the wing vibrates while the propeller revolves.

The most important function of the tail in flight is to balance the bird. It is of some assistance in steering, but a bird steers its course mostly by manipulation of the wings.

Scratching. With the exception of the aquatic birds and the ostrich, all the species of poultry belong to the group called by naturalists Rasores or Scratchers. Birds of this class have legs of moderate length and very strong, with toes terminating in a stout claw. Normally they have three toes upon which the foot rests when they are standing on a flat surface, and a fourth toe, like a thumb, which assists the other toes to grasp a perch. Some individual birds and some races of birds have the fourth or hind toe double. The leg of a bird is so constructed that when it is bent as the bird sits on a narrow support the toes contract and grasp the support and hold it without any effort on the part of the bird. Thus the bird is as secure in its position on a limb when asleep as if wide awake and looking out for itself.

In proportion to their ability to scratch, birds are able to find seeds and insects concealed among dead or living vegetation on the surface of the ground, and also to dig below the surface. Scratching capacity is most highly developed in the fowl. Compared to it the other land birds are very feeble scratchers, and do little damage by scratching if free to roam about. For ages the scratching propensity of fowls was regarded as a vice in them, but since people began to give special attention to poultry they have learned that fowls are much more contented and thrifty in confinement if their food is given them in a litter of leaves, straw, or shavings, in which they must scratch for it, and have also found that to some extent fowls may be used to cultivate crops while destroying insects and weeds among them.

Swimming. Capacity for swimming has an economic value in domestic birds because it adapts those possessing it to places which land birds rarely frequent. It will be shown when the different kinds of aquatic birds are described that each has its special place and use in domestication.

The swimming faculty in these birds is of further interest because of its relation to the development of the body plumage. If a land bird is placed in the water, the feathers are quickly saturated, the water penetrating to the skin. A duck or other swimming bird will remain in the water for hours without the water penetrating the feathers. This is commonly supposed to be due to the presence of a large amount of oil in the feathers, but the difference in the oiliness of the feathers of fowls and of ducks is not great enough to account for the difference in resistance to the penetration of water. The peculiar quality of the plumage of swimming birds is its density. If you take up a fowl and examine the plumage you will find that it is easy to part the feathers so that the skin can be seen. It may be done with the fingers, or even by blowing gently among the feathers with the mouth. Now try to separate the feathers of a duck so that the skin will be visible. You find it much harder, because the feathers are so thick and soft and at the same time so elastic. The familiar phrase "like water from a duck's back" is not especially appropriate. The feathers on the back of most birds are a very effective protection against rain. The feathers all over a duck are such poor conductors of water that it is hard to remove them by scalding. The structure of the plumage of swimming birds adds to their buoyancy in the water. They do not have to exert themselves to remain on the surface, but float like cork.

Foods and mode of digestion. All kinds of poultry and most of our common wild birds are omnivorous eaters, but the proportion of different foods usually taken is not the same in different kinds of birds. Some eat mostly grains, some mostly animal foods. Some can subsist entirely on grass if they can get it in a tender state; others eat very little grass. The scratching birds like a diet of about equal parts of grain, leaves, and insects. Pigeons and canaries live almost entirely on grains and seeds, but like a little green stuff occasionally.

Domestic birds which produce many eggs require special supplies of food containing lime to make the shells. Until within a few years it was universally believed—and it is still commonly supposed—that birds needed grit to take the place of the teeth nature did not give them, and assist in the grinding of the food in the gizzard. Many close observers now reject this idea because they find that birds supplied with digestible mineral foods do not eat those that are not digestible. A bird does not need teeth to grind its food, because it is softened in the crop and the gastric juice acts upon it before the grinding process begins.

Peculiarities of birds' eggs. The only animal foodstuff produced in a natural package, easily preserved and handled, is the egg. In the vegetable world we have a great many such things—fruits, seeds, roots, nuts, with coverings of various textures to protect the contents from the air. In all of these the material stored up is either for the nourishment of the seeds in the first stages of growth as plants, or for the nourishment of a new or special growth. An egg is the seed of an animal. All animals produce eggs, but in mammals the new life originating from the egg goes through the embryonic stages within the body of the parent, while in insects, fishes, reptiles, and birds the egg is laid by the creature producing it before the embryo begins to develop.

In mammals the embryo grows as a part of the body of the parent, the substances which build it up coming from the parent form as they are needed. In birds a tiny germ—the true egg—is put, with all the material needed for its development as an embryo, in a sealed package, which may be taken thousands of miles away from the parent, and, after lying dormant for weeks, may begin to grow as soon as the proper conditions of temperature are applied. The food value of the germ of an egg is inappreciable. We use the egg to get the material stored up in it for the young bird which would come from the germ.

Development of the egg. The method of the formation of an egg is very interesting. It is the same in all birds, but is most conveniently studied in fowls. If a laying hen is killed and the body is opened so that the internal organs can all be seen, one of the most conspicuous of these is a large, convoluted duct having its outlet at the vent. In this duct, which is called the oviduct, are eggs in various stages of formation. At its upper extremity, attached to the backbone, is a bunch of globular yellow substances which are at once identified as yolks of eggs in all sizes. The organ to which these are attached is the ovary. The smallest yolks are so small that they cannot be seen without a powerful microscope. These yolks are not germs, but as they grow the germ forms on one side of each yolk, where it appears as a small white spot.

When a yolk is full-grown it drops into the funnel-shaped mouth of the oviduct. Here it is inclosed in a membranous covering, called the chalazæ, and receives a coating of thick albumen. The function of the chalazæ is to keep the yolk suspended in the center of the egg. It does not merely inclose the yolk, but, twisted into cords, extends from either end and is attached to the outer membrane at the end of the egg.

After leaving the funnel the egg passes into a narrow part of the oviduct, called the isthmus, where it receives the membranous coverings which are found just inside the shell. From the isthmus it goes into the lowest part of the oviduct—the uterus. Here the shell is formed, and at the same time a thin albumen enters through the pores of the shell and the shell membranes and dilutes the thick albumen first deposited. After this process is completed the egg may be retained in the oviduct for some time. It is, however, usually laid within a few hours.

Rate and amount of egg production. In the wild state a bird, if not molested after it begins laying, produces a number of eggs varying in different kinds, according to the number of young that can be cared for, and then incubates them. If its first eggs are removed or destroyed, the bird lays more, usually changing the location of its nest. In domestication the eggs of most kinds of birds are removed from the nests daily as laid, and the birds lay many more eggs before they stop to incubate than they do in the wild state.

It is, and has been for ages, the common opinion that the wild birds and poultry, when first domesticated, were capable of laying only a small number of eggs each season, and that laying capacity has been enormously increased in domestication; but the oldest reports that we have of the amount of egg production indicate that the laying capacity of fowls was as great centuries ago as it is at the present time. Recent observations on wild birds in captivity show that even birds which pair and usually lay only a few eggs each season have a laying capacity at least equal to the ordinary production of hens. Quails in captivity have been known to lay about one hundred eggs in a season, and an English sparrow from which the eggs were taken as laid produced over sixty.

The constitutional capacity to produce ovules is now known to be far greater than the power of any bird to supply the material for the nourishment of germs through the embryonic stage. The principal factors in large egg production are abundance of food and great capacity for digesting and assimilating it.

Incubation. A bird before beginning to lay makes a nest. Some birds build very elaborate and curious nests; others merely put together a few sticks, or hollow out a little place on the ground. In birds that pair, the male and female work together to build the nest. Even in polygamous domestic birds like the fowl and the duck, a male will often make a nest for the females of his family and coax them to it as a cock pigeon does his mate.

If the birds are left to themselves and the eggs are not molested, an aërial bird will usually lay a number of eggs equal to the number of young the parents can feed as long as they require this attention, while a terrestrial or aquatic bird will usually lay as many eggs as she can cover. The desired number of eggs having been laid, the process of incubation by the parents begins.

The incubation of their eggs by birds is one of the most remarkable things in nature. We say that "instinct" leads birds to build their nests and to keep their eggs warm for a period varying from two weeks for small birds, to six weeks for the ostrich; but "instinct" is only a term to describe the apparently intelligent actions of the lower animals, which we say have not intelligence enough to know the reasons for the things that they do.

Fig. 3. Sitting hen

The mother of a young mammal knows that it came from herself, and she can see that it is like her and others of her kind. It at once seeks her care and responds to her attentions. The egg which a bird lays is as lifeless—to all appearances—as the stones which it often so closely resembles. Only after many days or weeks of tiresomely close attention does it produce a creature which can respond to the care lavished upon it. The birds incubating eggs not only give them the most unremitting attention, but those that fill their nests with eggs before beginning to incubate methodically turn the eggs and change their position in the nest, this being necessary because otherwise the eggs at the center of the nest would get too much heat and those at the outside would not get enough. A bird appears to know that if she begins to sit before she has finished laying, some of the eggs would be spoiled or would hatch before the others; and, as noted above, aërial birds seem to know better than to hatch more young than they can rear. But no bird seems to have any idea of the time required to hatch its eggs, or to notice the lapse of time, or to care whether the eggs upon which it sits are of its own kind or of some other kind, or to know whether the young when hatched are like or unlike itself. If eggs fail to hatch, domestic birds will, as a rule, remain on the nest until the eggs are taken away or until sheer exhaustion compels them to abandon the hopeless task. In domestication, however, those birds which continue laying most freely when their eggs are removed as laid, tend to lose the habit of incubation. Turkeys and geese will often begin to incubate after having laid about the number of eggs that they could cover. Many fowls will do the same, but most fowls lay for several months before attempting to incubate, and in many races not more than two or three per cent of the hens ever incubate.

Development of the embryo in a bird's egg. The condition required to produce a live bird from a fertile egg is the continuous application of a temperature of about 102 or 103 degrees Fahrenheit from the time the heat is first applied until the embryo is fully developed and ready to emerge from the shell. In nature the heat is applied by contact with the bodies of the parent birds. Development of life will start in an egg at about 10 degrees below the temperature required to maintain it, but at this temperature the germ soon dies. The temperature in incubation may occasionally go higher than 103 degrees or may be as low as 70 degrees for a short time without injury to the germ. Some germs will stand greater extremes of temperature than others, just as some living creatures will.

The first stages of the development of life in the egg of a bird may be observed by holding the eggs before a strong light in a darkened room. White-shelled eggs are the best for this purpose. In about thirty-six hours from the beginning of incubation it will be found that the germ has turned red, and little red veins radiate from it somewhat like the legs of a spider. For several days the egg is quite translucent and the yolk shows plainly. As the germ grows, the contents of the egg become clouded and dense, and the air space at the large end of the egg is clearly defined, the density being greatest near it. From the time that the egg becomes dense, observations of development must be made by breaking one or more eggs daily or every few days, according to the number available for observation.

The embryo grows until it fills the egg. The mere application of heat to the egg has gradually transformed that little germ and the yellow and white of egg into bones, flesh, skin (and, in some cases, down), and all the organs of a living creature. When the embryo has filled the shell, it lies curled up, usually with the head at the large end of the egg and the beak almost touching the shell, at about one third of the distance from the large to the small end of the egg. At the point of the beak of the young bird on the curved tip of the upper mandible is a small horny scale. Without this scale it would be hard for the embryo to break the shell because it cannot, as it lies, strike it a direct blow with the point of its beak. This scale is a remarkable character. Its only use is to help the bird out of the shell. A few days after exclusion it disappears.

If you take a hen's egg about the eighteenth or the nineteenth day of incubation and hold it closely in your hand, you may be able to feel the chick move. If your hand is a little bit cold, the chick is much more likely to squirm in the egg and may utter a peep. If, with the egg in a warm hand, you hold it to your ear, you will about this time hear an occasional tap, tap, caused by the chicken striking its beak against the shell. The tapping is kept up more or less steadily until the shell cracks where the point of the beak strikes it and a little piece is broken out. The chick usually rests awhile now,—perhaps for some hours,—then resumes the attack on the shell. It turns in the shell, breaking out little pieces as it turns, until there is a crack nearly all the way around, when, by pushing with its head and feet, it forces the shell apart and sprawls out of it.

The process is the same for all birds, except that those that take longest to develop in the shell take a longer rest after first breaking it. The young of aërial birds, which are naked when hatched, are ugly little things. Young poultry, too, are almost repulsive with their sprawling forms and the wet down plastered to the skin, but in a few hours they grow strong, the down dries and becomes fluffy, the bright little eyes seem to take in everything, and they are the most attractive of all baby animals.


CHAPTER III
SPECIES AND THEIR DIVISIONS IN DOMESTIC BIRDS

The three general classes of domestic birds include few species but many varieties, and, outside of the distinct varieties, an indefinite number of individual types. Where varieties are as numerous as in the fowl, which has about three hundred, and the pigeon, which has a much greater number, the differences between them are often very slight. Sometimes the form of a single small character is the only distinguishing feature. But, if this is a fixed character, the variety is distinct. Where there are so many varieties it is hard to make short, appropriate descriptive names for all, if considered simply as varieties. For such diversity there must be a more extended classification. Such a classification, growing gradually with the increase in the number of varieties, will not be consistent throughout. Hence to understand clearly the relations of the artificial divisions of species in domestication we must know what a species is and how these divisions arise.

Definition of species. Species are the natural divisions of living things. Each plant and animal species retains its distinctive character through long ages because the individuals composing it can produce perfect offspring only (if asexual) of themselves, or (if bisexual) with others of their species.

The self-isolation of species is well illustrated when similar plants grow together, as grasses in the same field and practically on the same spot; yet year after year all the old kinds are found and no new ones such as might come from a mixture of two kinds, if they would mix. In the higher animals, where the parent forms are of different sexes, they choose mates of their own kind, and so each species remains distinct; but if in a species there are many different types, such as we find in domestic fowls, the members of the species, when free to do so, mate as readily with types quite different from their own as with individuals exactly like them, and produce offspring of intermediate types with all the essential characters of the species. In domestication individuals of distinct yet similar species are sometimes mated and produce offspring called hybrids, but these are sterile. The mule, which is a hybrid between the ass and the mare, is the most familiar animal of this kind. Hybrid, or mule, cage birds are produced by crossing the canary with several allied species. Among other domestic birds hybrids are almost unknown.

Origin of species. Until near the close of the last century it was commonly believed that each species had been created in perfect form and that species were unchangeable; but long before that time some keen students of the natural sciences and close observers of the changes that take place in plants and animals in domestication had discovered that species were not perfectly stable and were changing slowly. Geologists established the fact that the earth, instead of being only a few thousand years old, had existed for countless centuries. Among fossil remains of creatures unlike any now known they had found also other forms which appeared to be prototypes of existing species. The idea that the forms of life now on the earth had come from earlier and somewhat different forms had occurred to several scientists more than a hundred years ago, but it was not until about 1860 that a satisfactory explanation of progressive development of forms of life was given to the world. This mode of creation is called evolution.

The theory of evolution is that partly through their own inherent tendency to vary and partly through the influence of external things which affect them, all organisms change slowly; that things of the same kind, separated and living under different conditions, may in time so change that they become separate species; and that this process may be repeated indefinitely, the number of species constantly increasing and becoming more diversified and more highly developed.

Such a theory would not be entitled to serious consideration unless it was known that the earth was millions of years old, because we know that races of fowls separated for over three thousand years (and perhaps twice as long) and developed into quite different varieties will breed together as readily as those of the same variety. But when it is certain that the earth is so old that there has been ample time for changes in living forms that would require periods of time beyond our comprehension, some of the relations of varieties and species of birds have an important bearing on the theory of evolution.

As in the case of fowls just noted, we find that domestic ducks of the same species, after a separation of several thousand years, breed freely together. But our domestic ducks are not, like the fowls, all of the same species, and if individuals of different species are paired they produce only a few weak hybrids. Our domestic geese are probably descended from two wild varieties, but races that were not brought together for thousands of years after they were domesticated are perfectly fertile together, while when mated with the American Wild Goose, which is not domesticated but will breed in captivity, they produce only hybrids. The general resemblance between geese and ducks is very striking, yet they will not breed together at all.

A comparison of these facts indicates that while three thousand, or even five or six thousand, years of separation may not be enough to break down the natural affinity of varieties of the same species, separation and difference of development will eventually make of varieties distinct species, a union of which will produce only hybrids, while a longer separation and further increase of differences makes the break between the species absolute and they will not breed together at all.

Natural varieties. A species having developed as a variety of an earlier species will continue to develop as one variety or as several varieties, according to conditions. If a part of a species becomes so separated from the rest that intercourse ceases, each division of the species may become a well-defined variety.

Varieties in domestication. How a species when domesticated breaks up into varieties is well illustrated by the case of the fowl. The original wild species has long disappeared, but there is good reason to suppose that in size and color it was something between a Brown Pit Game and a Brown Leghorn. The birds were smaller than most fowls seen in this country to-day. The prevailing color was a dull brown, because that color best conceals a small land bird from its enemies. Fowls that were domesticated and given good care and an abundance of food would usually grow larger than the wild stock. Thus if any person, or the people generally in any community, systematically gave their fowls good care, a variety of unusual size would be developed.

Different colors would also appear in the flocks of fowls, because the birds of unusual colors would be protected and preserved, instead of being destroyed as they usually are in the wild state. Other peculiarities, too, such as large combs, crests, and feathered legs, would be developed in some lands and neglected in others. This is how it happened that after thousands of years in domestication the races of fowls in different parts of the world were quite different in size and form, but alike in being of many colors.

From a species in this condition modern poultry breeders have made hundreds of distinct varieties. The easiest method of making a variety in domestication is to select specimens for breeding as near the desired type as possible, and to breed only from a few individuals in each generation which come nearest to the ideal type. In this way a variety that breeds quite true to the type may be established in from three or four to eight or ten years, according to the number of characters to be established as distinctive of the variety. Varieties are also made by crossing unlike individuals. This process is longer than the other, and sometimes requires a series of crosses to produce specimens approximating the ideal sought. After such specimens have been obtained the method is the same as in the first case. A variety is commonly considered to be well established when the greater part of the specimens produced are easily identified as of that variety. But no domestic variety is ever established in the sense that a species is. All are artificial, produced by compulsory separation and preserved only as long as it is continued.

Classification of domestic varieties of birds. Domestic varieties of all kinds of live stock were at first mostly shape-varieties; that is, the individuals of a variety were alike in shape but of various colors. This is the case still with some varieties. These shape-varieties are mostly the common types of certain countries or districts. Thus the Leghorn fowl is the common fowl of Italy, and the Houdan is a type common in a small district in France. Such shape-varieties are called breeds. When other types were made by crossing such breeds they also were called breeds.

When people first began to be interested in the improvement of live stock, the popular idea of a breed was that it was a domestic species, and there are still many people who hold this view. This popular misconception of the nature of a breed is responsible for much of the inconsistency and confusion in the ordinary classifications of domestic varieties. To it also is due the use of the term "variety" to apply especially to color-varieties, which are the principal divisions of breeds.

In the classification of domestic birds a variety is properly a color-variety of a breed. Thus in the Plymouth Rock breed there are six color-varieties—barred, white, buff, partridge, silver-penciled, and ermine (called Columbian); and in Fantail Pigeons there are six color-varieties—white, blue, black, red, yellow, and silver. Birds of the same breed (shape) and the same variety (color) may differ in some other character, as the form of the comb or the presence or absence of feathers in certain places. In accordance with such differences varieties are divided into subvarieties. Thus, in Leghorn Fowls the brown, white, and buff varieties have single-combed and rose-combed subvarieties.

In any breed, variety, or subvariety certain families are sometimes distinguished for general or special excellence of form or color. Such a family is called a strain.

Systematic mixtures of breeds and varieties. Although so many distinct varieties have been developed from common domestic stocks, the improved races do not always displace the mongrels. When the old mongrels disappear their place is often taken by a new mongrel stock produced by mixtures of the distinct breeds with each other and with the old mongrel race. The greater part of such stock is so mixed that its relation to any established breed could not be determined or expressed, but systematic mixtures are sometimes made, and to describe these the following terms are used: Crossbred—having parents of different, distinct breeds, varieties, or subvarieties. A Leghorn male mated with a Cochin female produces offspring each of which is in blood one half Leghorn and one half Cochin. Grade—having more than half of the blood of a breed.

If the offspring of a cross such as is described in the preceding paragraph are mated with birds of one of the parent breeds, the offspring of this mating will have three fourths of the blood of that breed. If these in turn are mated to birds of the same pure breed, the offspring will have seven eighths of the blood of that breed. Animals bred in this way are called grades until the process has been carried so far that they are practically pure-bred. Mongrel stock is often graded up in this way. As a rule stock that is seven eighths pure is not distinguishable from average pure stock of the same breed.

Pure-bred, thoroughbred, and standard-bred. A pure-bred animal is, strictly speaking, one having the blood only of the variety to which it belongs. From what has been said of the making of breeds and varieties it is plain that absolute purity of blood is not a universal attribute of well-bred domestic birds. A thoroughbred animal is one that is thoroughly bred for some purpose or to some type. A standard-bred animal is one that is bred especially to conform to requirements agreed upon by breeders and exhibitors.

A great deal of misapprehension and confusion in the use of these terms has been caused by the attitude of those who maintain that the term "thoroughbred," having been used as a name for highly bred running horses, cannot properly apply to any other kind of live stock, and that "pure-bred" should apply to all thoroughly bred races. The noun "Thoroughbred" is the name of a breed of horses. The adjective "thoroughbred" is common property. Writers on aviculture who wish to be accurate prefer it in many instances to "pure-bred" because absolute purity of blood is rare and is not of the importance in breeding that novices usually suppose. Not only are many new varieties made by crossing, but in long-established breeds outcrosses are regularly made to restore or intensify characters.

To illustrate the use of the three terms in application to a single breed: A stock of Light Brahmas might be kept pure for half a century, yet at the end of that period might have changed its type entirely. It might be so deteriorated that it was worth less than common mongrels; yet it is pure-bred stock. Another stock of the same variety might be bred for table qualities, egg-production, and the same principal color-characteristics of the variety, but without attention to the fine points of fancy breeding. Such a stock is thoroughbred but not standard-bred.


CHAPTER IV
FOWLS

The most useful of all birds is the common fowl, seen on almost every farm and in the back yards of many city and village homes. The fowl takes to the conditions of domestic life better than any other land bird. It is more cleanly in its habits, more productive, more intelligent, and more interesting than the duck, which ranks next in usefulness. Fowls supply nearly all the eggs and the greater part of the poultry meat that we use. Their feathers are of less value than those of ducks, geese, and turkeys. In the days when feather beds were common they were made usually of the body feathers of fowls. Now the feathers of fowls are used mostly for the cheaper grades of pillows and cushions, and in the making of feather boas and like articles. The wing and tail feathers have been much used for decorating ladies' hats, and since the use of small wild birds in millinery decorations has been prohibited, the hackle feathers of cocks are quite extensively used in trimming hats.

Description. Ordinary fowls are rather small land birds. The males at maturity weigh from four to five pounds each, and the females about a pound less. They are plump, rugged, and very active. If treated well they are bold, and with a little attention can easily be made very tame. If neglected and abused, they become shy and wild. The most striking peculiarities of the fowl are the fleshy comb and wattles which ornament the head, and the full tail which is usually carried well up and spread perpendicularly. The head appendages vary much in size and form. They are sometimes very small, but never entirely wanting. The carriage of the tail also varies, but except in a few breeds bred especially for low tails it is noticeably high as compared with that of other poultry. Fowls are readily distinguished from other birds by the voice. The male crows, the female cackles. These are their most common calls, but there are other notes—some common to both sexes, some peculiar to one—which are the same in all races of fowls. An abrupt, harsh croak warns the flock that one of their number has discerned a hawk or noticed something suspicious in the air. A slowly repeated cluck keeps the young brood advised of the location of their mother. If she finds a choice morsel of food, a rapid clicking sound calls them about her. When she settles down to brood them she calls them with a peculiar crooning note. The male also cackles when alarmed, and when he finds food calls his mates in the same way that the female calls her young under the same circumstances. Other poultry and sometimes even cats and dogs learn this call and respond to it. If the food discovered is something that a stronger animal wants, the bird making the call may lose it because of his eagerness to share the treasure with the members of his family.

In adult fowls the male and female are readily distinguished by differences in appearance as well as by the voice. The comb and wattles of the male are larger, and after he has completed his growth are always of the same size and a bright red in color. In the female the comb is much smaller than that of a male of the same family, and both size and color vary periodically, the comb and wattles being larger and the whole head brighter in color when the female is laying. The tail of the male is also much larger than that of the female and has long plumelike coverts. The feathers of his back and neck are long, narrow, and flowing, and in many varieties are much brighter in color than the corresponding feathers on the female. The male has a short, sharp spur on the inside of each leg, a little above the hind toe. Occasionally a female has spurs, but they are usually very small. With so many differences between male and female the sex of an adult fowl is apparent at a glance. In the young of breeds which have large combs the males begin to grow combs when quite small, and so the sex may be known when they are only a few weeks old. In other breeds the sex may not be distinguished with certainty until the birds are several months old, or, in some cases, until they are nearly full-grown.

The adult male fowl is called a cock, and also, in popular phrase, a rooster. The adult female fowl is called a hen. The word "hen" is the feminine form of hana, the Anglo-Saxon name for the cock. It is likely that the name "cock," which it is plain was taken from the first syllable of the crow of the bird, was gradually substituted for hana because it is shorter. Hana means "the singer." A young fowl is called a chicken until the sex can be distinguished. After that poultry fanciers call the young male a cockerel and the young female a pullet. The word "pullet" is also used by others, but the popular names for a cockerel are crower and young rooster. The word "cockerel," as is seen at a glance, is the diminutive of "cock." The word "pullet," sometimes spelled poulet, is a diminutive from the French poule, "a hen."

Origin of the fowl. Of the origin of the fowl we have no direct knowledge. It was fully domesticated long before the beginnings of history. There is no true wild race of fowls known. For a long time it was commonly held that the Gallus Bankiva, found in the jungles of India, was the ancestor of all the races of the domestic fowl, but this view was not accepted by some of the most careful investigators, and the most recent inquiries into the subject indicate that the so-called Gallus Bankiva is not a native wild species but a feral race, that is, a race developed in the wild from individuals escaped from domestication.

Appearance of the original wild species. The likeness of the fowls shown in ancient drawings to the ordinary unimproved stock in many parts of the world to-day shows that—except as by special breeding men have developed distinct races—fowls have not changed since the most remote times of which records exist. From the constancy of this type through this long period it is reasonably inferred that no marked change in the size and shape of the fowl had occurred in domestication in prehistoric times, and therefore that the original wild fowl very closely resembled fowls which may be seen wherever the influence of improved races has not changed the ordinary type. The particular point in which the wild species differed from a flock of ordinary domestic fowls was color. Domestic fowls, unless carefully bred for one color type, are usually of many colors. In the wild species, as a rule, only one color would be found, and that would be brown, which is the prevailing color among small land birds.

Distribution of fowls in ancient times. From drawings and descriptions on ancient tablets and from figures on old coins it appears that the fowl was familiar to the Babylonians seven thousand years ago, and that it was introduced into Egypt about 4600 b.c. Chinese tradition gives 1400 b.c. as the approximate date of the introduction of poultry into China from the West. At the time of the founding of Rome the fowl was well known throughout Northern Africa, and in the Mediterranean countries of Europe as far west as Italy and Sicily. It was also known in Japan at this time. Whether it was known in India is uncertain; if not, it was brought there soon after. It is supposed that immediately following their conquests in Central and Western Europe the Romans introduced their poultry into those regions. Thus, at about the beginning of the Christian Era, the fowl was known to all the civilized peoples of the Old World and had been introduced to the less civilized races of Europe.

Development of principal races of fowls. There is no evidence that any of the ancient civilized peoples made any effort to improve the fowl, nor have any improved races been produced in the lands where those civilizations flourished. Outside of this area many different types were gradually developed to suit the needs or the tastes of people in different countries and localities. Thus in the course of centuries were produced from the same original wild stock fowls as unlike as the massive Brahma, with feathered legs and feet, and the diminutive Game Bantam; the Leghorn, with its large comb, and the Polish, with only the rudiments of a comb and in its place a great ball of feathers; the Spanish, with monstrous development of the skin of the face, and the Silky, with dark skin and hairlike plumage. Except in a few limited districts these special types did not displace the ordinary type for many centuries. Until modern times they were hardly known outside of the districts or the countries where they originated. Of the details of their origin nothing is known. They were not of the highly specialized and finished types such as are bred by fanciers now. Their distinctive features had been established, but in comparatively crude form. The refining and perfecting of all these types has been the work of fanciers in Holland, Belgium, England, and America in modern times. These fanciers have also developed new races of more serviceable types.

How fowls were kept in old times. Less than a century ago it was quite a common practice among the cottagers of England and Scotland to keep their fowls in their cottages at night. Sometimes a loft, to which the birds had access by a ladder outside, was fitted up for them. Sometimes perches for the fowls were put in the living room of the cottage. Such practices seem to us wrong from a sanitary standpoint, but it is only within very recent times that people have given careful attention to sanitation, and in old times, when petty thieving was more common than it is now, there was a decided advantage in having such small domestic animals as poultry and pigs where they could not be disturbed without the owner's knowing it. The practice of keeping fowls in the owner's dwelling seems to have been confined to the poorer people, who had no large domestic animals for which they must provide suitable outbuildings. On large farms special houses were sometimes provided for poultry, but they were probably oftener housed with other animals, for few people thought it worth while to give them special attention.

Throughout all times and in all lands the common domestic birds have usually been the special charge of the women and children of a household. In some countries long-established custom makes the poultry the personal property of the wife. A traveler in Nubia about seventy years ago states that there the henhouse, as well as the hens, belonged to the wife, and if a man divorced his wife, as the custom permitted, she took all away with her.

The flocks of fowls were usually small in old times. It was only in areas adjacent to large cities that a surplus of poultry or eggs could be disposed of profitably, and as the fowls were almost always allowed the run of the dooryard, the barnyard, and the outbuildings, the number that could be tolerated, even on a large farm, was limited. As a rule the fowls were expected to get their living as they could, but in this they were not so much worse off than other live stock, or than their owners. But, while this was the ordinary state of the family flock of fowls, there were frequent exceptions. The housewife who is thrifty always manages affairs about the house better than the majority of her neighbors, and in older poultry literature there are occasional statements of the methods of those who were most successful with their fowls, which we may well suppose were methods that had been used for centuries.

Modern conditions and methods. About a hundred years ago people in England and America began to give more attention to poultry keeping, and to study how to make poultry (especially fowls) more profitable. This interest in poultry arose partly because of the increasing interest in agricultural matters and partly because eggs and poultry were becoming more important articles of food. Those who studied the situation found that there were two ways of making poultry more profitable. One way, which was open to all, was to give the birds better care; the other was to replace the ordinary fowls with fowls of an improved breed. So those who were much interested began to follow the practices of the most successful poultry keepers that they knew, and to introduce new breeds, and gradually great changes were made in the methods of producing poultry and in the types of fowls that were kept in places where the interest in poultry was marked.

Nearly all farmers now keep quite large flocks of fowls. Many farmers make the most of their living from poultry, and in some places nearly every farm is devoted primarily to the production of eggs and of poultry for the table. Fowls receive most attention, although, as we shall see, some of the largest and most profitable farms are engaged in producing ducks. In the suburbs of cities and in villages all over the land many people keep more fowls now than the average farmer did in old times. These city poultry keepers often give a great deal of time to their fowls and still either lose money on them or make very small wages for the time given to this work, because they try to keep too many in a small space, or to keep more than they have time to care for properly.

The breeding of fancy fowls is also an important pursuit. Those who engage in this line on a large scale locate on farms, but many of the smaller breeders live in towns, and the greater number of the amateur fanciers who breed fine fowls for pleasure are city people.

On large poultry farms the work is usually done by men. There are many small plants operated by women. The ordinary farm and family flocks are cared for by women and children much oftener than by men, because, even when the men are interested in poultry, other work takes the farmer away from the vicinity of the house, and the city man away from home, so much that they cannot look after poultry as closely as is necessary to get the best results. Many women like to have the care of a small flock of fowls, because it takes them outdoors for a few minutes at intervals every day, and the eggs and poultry sold may bring in a considerable amount of pin money. Many boys, while attending the grammar and high schools, earn money by keeping a flock of fowls. Some have saved enough in this way to pay expenses at college for a year or more, or to give them a start in a small business. When there are both boys and girls in a family, such outdoor work usually falls to the lot of a boy. A girl can do just as well if she has the opportunity and takes an interest in the work.

Native fowls in America. To appreciate the influence of improved races of fowls from various parts of the Old World upon the development of poultry culture in America, we must know what the fowls in this country were like when poultry keepers here began to see the advantages of keeping better stock, and must learn something of the history of the improved races in the countries from which they came.

Fig. 25. Dominique cockerel. (Photograph from W. H. Davenport, Coleraine, Massachusetts)

When we speak of native fowls in America we mean fowls derived from the stocks brought here by the early settlers. The fowl was not known in the Western Hemisphere until it was brought here by Europeans. Britain, France, Spain, Holland, and Sweden all sent colonists to America, and from each of these countries came, no doubt, some of the ordinary fowls of that country. Perhaps improved varieties came from some of these lands in early colonial times, but the only breeds that retained their identity sufficiently to have distinctive names were the Game Fowls, which came mostly from England, and the Dominiques (bluish-gray barred fowls which probably came from Holland or from the north of France, where fowls of this type were common).

The Game Fowls, being prized for the sport of cockfighting, were often bred with great care, but the Dominique fowls (also called cuckoo fowls and hawk-colored fowls) were mixed with other stock, and the name was commonly given to any fowl of that color, until after the improvement of fowls began. Then some people collected flocks of fowls of this color and bred them for uniformity in other characters. Well-bred fowls, however, were comparatively rare. Most of the stock all through the country was of the little mongrel type until about the middle of the last century. Then that type began to disappear from New England, New York, New Jersey, and eastern Pennsylvania. It remained longer in the Northern states west of the Allegheny Mountains and a generation ago was still the most common type in the upper Mississippi Valley. It is now unknown outside of the Southern states, and within ten or twenty years it will disappear entirely.

Old European races of fowls. With the exception of the Leghorn, most of the distinct breeds of European origin were brought from England, and the types introduced were not the types as developed in the places where the breeds (other than English breeds) originated, but those types as modified by English fanciers. In America, again, most of these breeds have been slightly changed to conform to the ideas of American fanciers. So, while the breed characters are still the same as in the original stocks, the pupil looking at birds of these breeds to-day must not suppose that it was just such birds that came to this country from seventy to a hundred years ago, or that, if he went to the countries where those races originated, he would find birds just like those he had seen at home. Except in the case of the distinctly English breeds, such as the Dorking and the Cornish Indian Game, which are bred to greater perfection in their native land than elsewhere, he would find most of the European races not so highly developed in the countries where they originated as in England and America, where fanciers are more numerous.

Italian fowls. Strictly speaking, the Italian fowls in Italy are not an improved race. The fowl which is known in this country as the Leghorn fowl (because the first specimens brought here came from the port of Leghorn) is the common fowl of Italy and has changed very little since it was introduced into that country thousands of years ago. It is found there in all colors, and mostly with a single comb. The Italian type is of particular interest, not only because of its influence in modern times, but because from it were probably derived most of the other European races. Italian fowls were first brought to this country about 1835, but did not attract popular attention until twenty-five or thirty years later.

English races of fowls. It is supposed that fowls were introduced into Britain from Italy shortly after the Roman conquest. The type was probably very like that of ordinary Leghorn fowls of our own time, but with smaller combs. From such stock the English developed two very different races, the Pit Game and the Dorking. Game fowls were bred in all parts of the kingdom, but the Dorkings were a local breed developed by the people in the vicinity of the town of Dorking, where from very early times the growing of poultry for the London market was an important local industry. Each in its way, these two breeds represent the highest skill in breeding. In the Old English Game Fowl, symmetry, strength, endurance, and courage were combined to perfection. The Dorking is the finest type of table fowl that has ever been produced.

German and Dutch races. The breeds now known as Hamburgs and Polish are of peculiar interest to a student of the evolution of races of fowls, because they present some characters not readily derived from the primitive type of the fowl. The feather markings of some varieties of both these breeds are unlike those of other races, and are markings which would not be likely to become established unless the fowls were bred systematically for that purpose. So, too, with the large crest of the Polish fowl: to carry it the structure of the head must be changed. Such changes require systematic breeding for a long period. Dutch and German artists of the sixteenth century painted many farmyard scenes showing fowls of both these types, frequently in flocks with common fowls and with some that appear to be a mixture. To any one versed in the breeding of poultry this indicates that these peculiar types had been made by very skillful breeders long before. The most reasonable supposition is that these breeders were monks in the monasteries of Central Europe. Throughout the Middle Ages the monks of Europe, more than any other class of men, worked for improvement in agriculture as well as for the advancement of learning.

French races. The Houdan is the only French breed well known in America. It is of the Polish type, but heavier, and the plumage is mottled irregularly, not distinctly marked as in the party-colored varieties of Polish. The breed takes its name from the town of Houdan, the center of a district in which this is the common type of fowl.

Spanish races. The fowls of Spanish origin well known outside of Spain are the White-faced Black Spanish, the Black Minorca, and the Blue Andalusian. The fowls of Spain at the present time are mostly of the Italian type, with black (or in some districts blue) the predominant color. The Black Spanish seems to have been known in Holland and England for two hundred years or more. In Spain the white face is but moderately developed. The monstrous exaggeration of this character began in Holland and was carried to the extreme by British fanciers who admired it.

The Black Minorca is supposed to have been brought to England direct from Spain about a century ago. There it was bred to much greater size, with the comb often so large that it was a burden to the fowl. Blue Andalusians, at first called Blue Spanish and Blue Minorcas, were first known in England about 1850.

Asiatic races of fowls. The evolution of races of fowls in the Orient gave some general results strikingly different from those in Europe. As far as is known, after the introduction of fowls into China and India some thousand years ago the stock which went to those countries and that which descended from it was completely isolated from the fowls of Western Asia, Africa, and Europe until the eighteenth century. When commerce between Europe, India, and the East Indies began, the Europeans found in these countries fowls of a much more rugged type than those of Europe. Some of these fowls were much larger than any that the visitors had seen. The Aseel of India was a small but very strong, stocky type of Game. Among the Malayans the common fowl was a large, coarse type of Game. The hens of these breeds laid eggs of a reddish-brown color, while hens of all the races of Europe laid white eggs. Birds of both these types were taken to England early in the last century, and perhaps in small numbers before that time.

Chinese races. In China a type of fowl in some ways much like the Malay, in others quite different, had been developed as the common stock of the country. They were about as tall as the Malays, much heavier, and very quiet and docile. They were of various colors, had feathers on the shanks and feet, and laid brown eggs. Some of these fowls were brought to America in sailing vessels very early in the last century and occasionally after that until the middle of the century, but attracted no attention, for the birds were brought in small numbers for friends of sailors or for persons particularly interested in poultry, and at that time there was no means of communication between fanciers in different localities.

Japanese races. Although the Japanese races of fowls had no particular influence on the development of poultry culture in America, they are of great interest in a study of poultry types, because, when intercourse between Japan and Western nations began, it was found that the ordinary fowls of Japan were much like the ordinary fowls of Europe and America, and not, as would be expected, like the fowls of China. This indicated that there had been no exchange of fowls between China and Japan after the type in China became changed. It also affords strong evidence that the fowls of India and China, although so changed, were originally like the European and Japanese common fowls. The special races developed in Japan were Game Fowls, more like the European than the Malay type; a long-tailed fowl, very much like the Leghorn in other respects; and the very short-legged Japanese Bantam.

The "hen-fever" period. We are all familiar with the phrase "the hen fever" and with its application to persons intensely interested in poultry, but few know how it originated. The interest in better poultry that had been slowly growing in the Eastern states culminated in 1849 in an exhibition in the Public Garden in Boston, to which fanciers from eastern Massachusetts, Rhode Island, and eastern Connecticut brought their choicest and rarest specimens. This was the first poultry show held in America. Nearly fifteen hundred birds were exhibited, and the exhibitors numbered over two hundred. There were a few birds of other kinds, but fowls made by far the greater part of the show. All the principal races of Europe and Asia were represented. Most of the exhibitors lived in the immediate vicinity of Boston. About ten thousand people attended this exhibition.

Such an event created a great sensation. Newspaper reports of it reached all parts of the country. The Chinese fowls, so large when compared with others, were most noticed. At once a great demand for these fowls and for their eggs arose, and prices for fancy poultry, which previously had been but little higher than prices for common poultry, rose so high that those who paid such prices for fowls were commonly regarded as monomaniacs. While the interest was not as great in other kinds of fowls as in the Shanghais, Cochin Chinas, and "Brahmaputras," as they were then called, all shared in the boom, and within a few years there was hardly a community in the northeastern part of the United States where there was not some one keeping highly bred fowls. When the interest became general, the famous showman, P. T. Barnum, promoted a show of poultry in the American Museum in New York City. Many celebrated men became interested in fine poultry. Daniel Webster had been one of the exhibitors at the first show in 1849. The noted temperance lecturer, John B. Gough, was a very enthusiastic fancier.

After a few years the excitement began to subside, and most people supposed that it was about to die, never to revive. A Mr. Burnham, who had been one of the most energetic promoters of Asiatic fowls, and had made a small fortune while the boom lasted, had so little confidence in the permanence of the poultry fancy that he published a book called "The History of the Hen Fever," which presented the whole movement as a humbug skillfully engineered by himself. This book was very widely read, and the phrase "the hen fever," applying to enthusiastic amateur poultry keepers, came into common use.

Subsequent developments showed that those who had supposed that the interest in fine poultry was only a passing fad were wrong. The true reason for its decline at that time was that the nation was approaching a crisis in its history and a civil war. When the war was over, the interest in poultry revived at once, and has steadily increased ever since. The prices for fine specimens, which were considered absurd in the days of the hen fever, are now ordinary prices for stock of high quality.

How the American breeds arose. It is natural to suppose that with such a variety of types of fowls, from so many lands, there was no occasion for Americans to make any new breeds. If, however, you look critically at the foreign breeds, you may notice that not one of them had been developed with reference to the simple requirements of the ordinary farmer and poultry keeper. It was the increasing demand for eggs and poultry for market that had given the first impulse to the interest in special breeds. The first claim made for each of these was that it was a better layer than the ordinary fowl. In general, these claims were true, but farmers and others who were interested primarily in producing eggs and poultry for the table were rather indifferent to the foreign breeds, because, among them all, there was not one as well adapted to the ordinary American poultry keeper's needs as the old Dominique or as the occasional flocks of the old native stock that had been bred with some attention to size and to uniformity in other characters.
