"Poultry" can be defined as domestic fowls, including chickens, turkeys, geese and ducks, raised for the production of meat or eggs and the word is also used for the flesh of these birds used as food. The Encyclopædia Britannica lists the same bird groups but also includes guinea fowl and squabs (young pigeons).Poultry are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae, especially the order Galliformes.Eggs are not included. They belong in the meat, poultry, fish, and eggs category, and are considered animal products. ... Eggs, on the other hand, come from chickens, which are classified as birds.All of the different types of poultry can be organized into four categories: landfowl, waterfowl, game and others.
