Baby hens are called pullets and are distinguished from baby roosters, which are called cockerels, by the shape of their tail feathers when the chicks are approximately three months old. The saddle or tail feathers on a pullet are rounded, and cockerels have long pointy saddles.
Hens are highly sociable animals that live in flocks. Hens use a pecking order among themselves that determines which hens get access to resources, such as food and water, first. The peak egg-laying time for hens is spring and summer, and many farmers install lights to trick the hens into producing eggs consistently all year long.
