i would be afraid with an auto door opener and closer, that there could be many things to go wrong. Such as, what if it didn't work one night? Or what if a chicken is sitting in the doorway and the door closes on them? Or what if the door closed after a predator got into the coop and the chickens couldn't get out? (Maybe i'm just a worry wart)
i know it's a chore to open coop doors in the morning (especially when you want to stay snugged in bed) then close them up at night. But for me, that's the only way i can be sure everyone is safe in bed, and then coming out healthy-looking in the morning.
