I have read on this message board that anything greater than one inch in terms of an opening in your coop invites weasels and rats. What about a one inch STRIP around a door? I built two A-frame coops and the doors were really difficult for me. As a result, I have about a one inch strip that is bothering me. I keep worrying about it. I have 20 Golden Campines in there now. Is the rule a one inch square, or a one inch strip? I have only seen pictures of weasels on here, and haven't seen rats around here.
