The chicken is a type of domesticated fowl, a subspecies of the red junglefowl. It's one of the most common and broadly distributed domestic animals, with a whole population of more than 19 billion as of the late 2000s. There are many more chickens than any other bird or domesticated fowl. Humans keep chickens primarily as a source of food, consuming both their meat and eggs, and, strangely and more rarely as pets.
Natural behaviour of the ChickenEdit
Chickens prefer to be kept in groups, like a lot of domesticated animals, and a group of chickens is called a flock. They sleep a deep sleep, and this makes them vulnerable to predators, for they aren't protected.
