Does anyone have or had an automatic coop door. The type with a light sensor, opens a few mins. after sunrise, closes a few mins. after sunset... At first I laughed at the idea of paying $250 or whatever it is, but now after reading a story of a raccoon attack not long after sunset, it has me thinking twice. At times, I'll return home after sunset, and I'm worried until I get back and shut the small coop door. One question I have is this: these doors, and others, are slide up doors. Is a raccoon smart enough to slide the door up and get inside? I've been screwing mine shut each night for security.
