They would just use the coop for roosting, laying eggs, and staying in while raining (during winter). It is 6ft wide, 4ft long, has 6 nesting boxes, and about 18ft of roosting. Right now I have 12 large breed hens, that roost and lay in the coop, and have about a half acre or more to roam free. how many more do you think I could fit? I am not planning on getting any more soon, but when their laying season is over I ant to get new hens. Thankyou!
