It is not necessary to give the fowls water when there is snow on the ground. Delicate fowls that are accustomed to close confinement may not be able to stand running out on the snow, but if they have a comfortable house, with a good supply of litter on the floor, and are free to go and come at will, rugged birds that are out in all kinds of weather are not in the least hurt by going out on snow and ice and wet ground in cold weather, and will usually take snow in preference to water when they can get it. When the ground is bare and frozen, water or finely chipped ice should be supplied. In extreme cold weather the latter is better, because the water soon freezes and the fowls go thirsty until a fresh supply is given them.

Reproducing the flock. Fowls are short-lived creatures. They mature in less than a year; their period of greatest productiveness is usually over before they are two years old, and only a very small proportion of a flock are worth keeping after that. Hence the entire stock of fowls on a farm is renewed in two years. Most farmers intend to kill off all their two-year-old hens each year, thus keeping up the number in the flock by growing annually about as many young birds as there are hens in the flock. To allow for losses, for an excess of males, and for inferior pullets which are not worth keeping for layers, it is necessary to hatch about four times as many chickens as are to be reserved.
The hatching season. Most of the chickens reared on farms are hatched in the spring months. The late-hatched chickens are nearly all from hens that steal their nests. People on farms do not want late chickens; among so many larger ones a few small birds have very little chance to make good growth. But those who have a place to keep a few early chickens and time to take care of them often set a few hens in the winter. Eggs will hatch at any season of the year, and chickens will grow if they get proper care; but there is a comparatively short season in the spring when eggs hatch better and chickens grow better than at any other time, and the easiest way to get a given number of good chickens that will be full-grown at the beginning of winter is to hatch them in this natural hatching season. This season cannot be exactly defined, because it varies according to latitude and also from year to year according to the weather. Perhaps the best general rule is to have the first chicks hatch when the grass is beginning to grow. To effect this the hens must be set three weeks earlier, when there may be no signs of spring. No one can time hatches to a natural phenomenon of this kind with certainty, but by planning with reference to the advance of spring in a normal season, the first hatches are usually brought very near to the desired time.
Broody hens. When a hen wants to incubate eggs, or, as the common phrase is, to sit, she remains on her nest continuously and, unless very shy, will not leave it when approached and will resent any interference. The hen is then said to be broody. Because the broody hen makes a clucking noise, she is sometimes called a clucking hen. Hens that are shy when they begin to cluck, and that fly from the nest when approached, usually become tame and allow themselves to be handled after a few days. Broody hens cannot always be obtained at the time they are wanted. In that case there is nothing to do but wait, or try to buy, hire, or borrow them. There is no way of forcing or inducing hens to become broody before they would do so of their own accord. When broody hens are hard to get, people think that hatching with incubators will relieve them of trouble and prevent delay, but the incubator, too, has its uncertainties. Success in artificial hatching requires careful attention to the operation of the incubator and good judgment in adjusting and regulating it.
