I have a 5 x 10 coop that has a 5 x 4 box that includes the nesting boxes for my three hens. (This box has a floor which is about 3 1/2 feet off the ground and I have two doors on it to clean it out and such.) I started noticing that I do not have a place for the hens to roost or perch. I guess they sleep in the box pretty well but I wonder if I need some kind of roosting place for them. If so what would be a good place to put in a coop this size?
