The area we are putting the coop isn't quite level and I don't really have an easy way to level it. Does it matter if it's sitting at a slight angle? It's not going to be a very big angle. If it's not ok, what do you suggest? I was thinking of putting the lower end up on cement blocks but then I wasn't sure about keeping it predator-proof. Would hardware cloth work for the gap? As for aprons, do they need to be buried? How far out from the coop should they go? Thanks!
