We are going build our coop over an existing patio slab. The run will be across dirt and grass. It will be tall enough for you to walk in normally. Basically, a small shed size. Would it just be easier to build a shed with a hole on the side leading into the run? The run would be enclosed with hardwire cloth as suggested. What kind of bedding would be best? I see coops with swings. Should I get one for the chickens? I live in New Mexico. It gets hot. Should I hook up a fan or an a/c?
