DH had made me an excellent coop...8x10 , two windows and 4 nesting boxes that I can open from the outside of the coop. He even used tin on the outside so it matches the other buildings. My questions..........I don't think we need to insulate it, and I don't think I need electric. I live in Minnesota and it gets pretty cold. My plan was even to leave the front part open with just a screen as it faces south. I will use deep liter this winter and I put all the perching roosts above the nesting boxes with easy clean up underneath...its predator proof. How am I doing? Have I got the basic's down?
