I would cover part of the roof, add a perch and a small nesting box. I would also add hardware cloth all the way around to reinforce it, then park it at night on top of a piece of hardware cloth on the ground to protect from diggers. Do you think it's "sufficient"? I'd like a coop but have no carpentry skills nor tools. Hopefully, a handy friend will be able to turn our under-used playset into a coop, but until then....
