What is your experience with the automatic chicken doors aside from the convenience aspect? I'm trying to decide if I want to go with them or the traditional way. We live in a rural area in MO. Predators are an issue. We have a huge coyote population, hawks, eagles, raccoons, etc. They will have a covered run. I'll probably free range only when I can supervise. (At least to start with) No electricity in the coop so it would run off of solar. Thanks in advance for your replies!
