After deciding that an automatic door would put us at ease in the evening when no one is around to shut the man door at dusk, we purchased an ADOR1. It works, but the chickens are being stubborn. Only 3 hens and 5 babies have figured it out. The remaining 2 roosters and 12 hens would rather roost on the railing than go inside. We keep the main door closed so they don't have a choice, and I've coaxed them with treats, and keeping the light on in the coop, but they aren't catching on. Any helpful hints would be appreciated The photo to the left is my coop.
