Pens for Hens is a term used to describe a type of chicken coop. It is a structure that provides chickens with a safe and secure environment to live in, while also allowing them to roam freely. The pens are usually made from wood or metal and have an open top, allowing the chickens to come and go as they please. The term 'pens for hens' is derived from the fact that the structure resembles a pen, providing the chickens with a place to call home.
