Do you have any type of latches or ideas to keep a chicken door closed tight but easy to latch and un-latch? Ideally I would like something that keeps the draft away, and easy to latch. Our chicken door is always getting wood chips in the door frame, making it hard to shut as it gets tighter with the junk in there. It's in a harder to reach spot to clean it out. (I have a door shoot/walkway thing with a rope to open the door. I don't mind too much, but when I go away I want it to be easy for our neighbor who is older. Is there any type of set up that would draw it in tight by leverage?
