What is a roost?

Answer 1

It's a bird nest

Actually it's the place a bird will rest/sleep overnight, not necessarily a nest (juveniles and unpaired birds have to sleep somewhere, and that's called a roost). Chickens "roost" - because they don't "nest" as such.

Answer 2

A roost is a place where birds, especially chickens or other domestic fowl, rest or sleep. It typically consists of a perch or elevated platform that allows the birds to roost off the ground. Roosts are important for bird safety and comfort.

Answer 3

The domestic roosters habitat will be the barn yard. depending on how the farm is kept the rooster may have woods and vegetation or it can be a bare lot.

Answer 4

A roost is where birds rest or sleep together, such as a tree or a man-made structure. Roosts can contain hundreds of birds.
