what is habited and use of hen

Answer 1

The chicken (Gallus gallus domesticus) is a type of domesticated fowl, a subspecies of the red junglefowl. It is one of the most common and widespread domestic animals, with a total population of more than 19 billion as of 2011. There are more chickens in the world than any other bird or domesticated fowl.[1] Humans keep chickens primarily as a source of food (consuming both their meatand eggs) and, less commonly, as pets. Originally raised for cockfighting or for special ceremonies, chickens were not kept for food until the Hellenistic period (fourth–second centuries BCE).[2][3]
