Mine also hear the screen door and start yelling. I keeping oilling it so I can sneak out but it doesn't last.It's funny you should mention the screen door setting them off. The other day I had to put the hens in the big coop for safety while i was out and tradies were working. When I got home i went from the car to the coop to let them out and asked the tradies if they'd been fretting all day: no, they started fretting only when they heard the car!
