Domestic birds such as chickens, turkeys, ducks, and geese. They were domesticated for meat and eggs by early farmers in China, Europe, Egypt, and the Americas. Chickens were domesticated from the Southeast Asian jungle fowl Gallus gallus and then raised in the East as well as the West. Turkeys are New World birds, domesticated in ancient Mexico. Geese and ducks were domesticated in Egypt, China, and Europe.

Good egg-laying breeds of chicken are Leghorns, Minorcas, and Anconas; varieties most suitable for eating are Dorkings, Australorps, Brahmas, and Cornish; those useful for both purposes are Orpingtons, Rhode Island Reds, Wyandottes, Plymouth Rocks, and Jersey White Giants. Most farm poultry are hybrids, selectively crossbred for certain characteristics, including feathers and down.

Factory farming
Since World War II, the development of battery-produced eggs and the intensive breeding of broiler fowls and turkeys has roused a public outcry against ‘factory’ methods of farming. The birds are often kept constantly in small cages, have their beaks and claws removed to prevent them from pecking their neighbours, and are given feed containing growth hormones and antibacterial drugs, which eventually make their way up the food chain to humans. Factory farming has led to a growing interest in deep-litter and free-range systems, although these account for only a small percentage of total production.
