Chickens are one of the most widespread domestic animal, usually for their eggs or meat, but they are also kept as pets. They are a subspecies of the red junglefowl, which is native to tropical rainforests in Asia. Chickens have a reputation for being dumb, but they are actually more observant than they might get credit for. They make many more sounds than the classic chicken calls, with each vocalization having distinct meaning. Chickens can also learn and recognize faces.
