I have a small playhouse type building with no windows or door and i also have an eight by five structure that has no roof and all open sides with a door. The sides are surrounded with something like chicken wire. Hubby wanted to convert the eight by five but without adding real walls so the chickens would be exposed all year long. I think we should convert the playhouse so the chickens have ventilation but are safe from weather and predators....i am right aren't I? I mean you can't just leave them exposed like that can you? Any thoughts and advice on conversion much appreciated!
