We've upgraded to a new coop and are trying to sort out the pop door, which folds down with the chicken steps on the other side of the door. We'd like to put something there we can shut without entering what will be the run and without lifting up the steps. We've also considered an automatic door on the inside, but that presents problems as I see it, given the structure inside the coop. I'm not mechanically/engineering inclined and are hoping the ingenuity of folks here can help us out with ideas.
