My husband made me an automatic chicken door using steel plate, timers, and an actuator. The chickens have been using it for about a month now with no problems. Tonight I went to make sure everything was ok and found a pullet squished by the door. This type of door seems pretty popular so has anyone else had this problem? I guess she decided to roost in the doorway and didn't move out of the way even though the door takes a minute to close and makes a lot of noise. Any idea on how to keep them from roosting in the doorway?
