We live in DE. So when we built the coop we made it fox proof. When I made the door I made it so in the summer every other pc of 1x4 come out(12"s high , 5 ft off the ground).It was for ventilation. Never assumed a raccoon would be able to get up there and in , but it did. So if your making a new coop, keep all predators in mind even if you haven't seen them in your yard.
