Hello, I'm trying to decide how high to place the roost and the nesting boxes. I am finally getting my coop underway. The chicks won't be in the hen house until they get their feathers, but I'm still not sure how high to place the roost. I have read to put it at least 1 foot from the roof but that seems high for young hens. My roof is 7 1/2 ft at the apex! should I put two? One lower and the other one higher for when they get older? What I read about the nest boxes is at least 2 feet off the floor.
