Fowl shelter is a term used to describe a structure that provides protection and shelter for birds, such as chickens, ducks, geese, and other poultry. The most common type of fowl shelter is a ROOST, which is a structure with perches or shelves for the birds to rest on. Roosts are typically made from wood, metal, or plastic, and can be either open-air or enclosed. They provide protection from predators and the elements, and also help keep the birds warm in cold weather.
