After reading several accounts of people locking themselves in the run, I can totally see that happening to me. So as we are nearing completion of the run and I am about to build the door and hang it, what kind of latch should I get? I want to make it as hard as possible for raccoons to gain access that way. So I was thinking perhaps one of those sliding ones with eyes that you can slip a numeric padlock through. But I'm not sure if that would be impractical and more of a bother than a help. Will raccoons figure self latching (the type that are normally on garden gates) latches out? Can they just lift the latch and get in? I am assuming that I could run a chain to the inside of the coop to pull on should this accidentally close on itself. Any other practical ideas?
