We are turning this existing shed into a coop, I've googled myself out trying to think of ideas, but if anyone can think of something. Ideally, we still need some storage, mostly just for a push mower, so i'd like to split the shed inside, 70/30, 70 going to the four chickens. with the run attached to it. Should I put the door at the side, or put another one at the back, skylights for ventilation etc. Ideas?
