I live in Texas. I'm not worried about my chicks freezing to death. But there's no reason they should be uncomfortable because of my stupidity. So , could someone tell me if this will work. Here's a pic. The door faces east, to the left is south, to the right is north. The north wall has no windows some gap between boards that's all. The roost faces east . The chickens can roost & look out of the window. The coop is under a big hackberry tree because our summers are long & very hot. What ya think ?
