The chicken (Gallus gallus domesticus) is a domesticated junglefowl species, with attributes of wild species such as the gray and the Ceylon junglefowl [1] that are originally from Southeast Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. The chicken domesticated for its meat are Broilers and for its eggs are Layers.
