I have a pullet shut automatic chicken door which I ABSOLUTELY love. It has the photosensitive eye so it opens at dawn and closes at dusks. However, last night all three ended up locked out and tonight one was locked out. I guess they figure they should not have to be inside by 5:15 when the door closes... Is anyone else having this problem with their automatic doors? Mine can be manually programmed so I guess I will override the photo sensor and leave the door open longer.
