Several species of wild birds known as guinea fowl are found in Africa, and derive their name from Guinea, which is situated on the West Coast of that continent. From one of these wild species (Numida meleagris) the common domesticated guineas are descended. They have long been domesticated, having been raised as table birds by the ancient Greeks and Romans, and were introduced into this country by the early settlers. In Africa, where there are still many wild flocks, they are highly prized by hunters as game birds, and in England they sometimes are used to stock game preserves. Even in this country a few flocks left to shift for themselves have become so wild as to afford excellent hunting.
Domesticated guinea fowl are of three varieties—Pearl, White, and Lavender. The Pearl is by far the most popular. It has a purplish-gray plumage regularly dotted or “pearled” with white and is so handsome that frequently the feathers are used for ornamental purposes. The White guinea fowl ([fig. 1]) is of pure-white plumage, and the skin is somewhat lighter in color than in the Pearl variety. Lavender guineas resemble those of the Pearl variety, except that the plumage is of a light gray or lavender, regularly dotted with white instead of a dark or purplish gray dotted with white. By crossing the Pearl or Lavender varieties with the White, what is known as the “Splashed” guinea is produced, the breast and flight feathers being white and the remainder of the plumage being Pearl or Lavender ([fig. 2]). Crosses between guinea fowl and other poultry, particularly chickens and less commonly turkeys, are not unknown, but such birds without exception are sterile.
The young guinea chicks are very attractive, those of the Pearl variety resembling young quail. They are brown in color, the under part of the body being lighter than the rest, while the beak and legs are red. The first feathers are brown, but these are replaced gradually by the “pearled” feathers until at about 2 months of age the brown feathers have disappeared completely. About this time also the wattles and helmet begin to make an appearance.
As yet no standard of perfection has been set for guinea fowl, the birds not being recognized by the American Poultry Association. They are exhibited at poultry shows throughout the country, however, and most of these shows offer prizes for the best birds. In judging guinea fowl, the points regarded as most important are good size and uniform color. White flight feathers in the Pearl and Lavender varieties are the most common defects. In weight, guineas average from 3 to 4 pounds at maturity for both male and female.
Distinguishing Sex
The male and the female guinea fowl differ so little in appearance that many persons have considerable difficulty in making a distinction. Indeed, it often happens that those who are inexperienced in raising these fowl will unknowingly keep all males or all females as breeding stock. Usually the males can be distinguished by their larger helmet and wattles and coarser head ([fig. 3]), but to be positive one should listen to the cry made by each bird. That of the female resembles “buckwheat, buckwheat,” and is decidedly different from the one-syllable shriek of the male. When excited, both the male and the female emit one-syllable cries, but at no time does the male imitate the cry of “buckwheat, buckwheat.” Sex can be distinguished by this difference in the cry of the male and female when the birds are about 2 months old.
Breeding
Like quail and most other wild birds, guinea fowls in their wild state mate in pairs, and this tendency prevails among domesticated guineas also, provided the males and females are equal in number. As the breeding season approaches, one pair after another separates from the remainder of the flock and ranges off in the fields in search of a suitable nesting place. Once mated in this way, the male usually remains with his mate throughout the laying season, standing guard somewhere near the nest while the hen is laying and ready to warn her of any approaching danger. However, it is not necessary to mate them in pairs under domestic conditions to secure fertile eggs, and most breeders keep but one male for every three or four females. When mated in this way the hens are more apt to lay near home, and several usually lay in the same nest, thus making it much easier to find the nests and gather the eggs.
