Situation Information: - I have chickens. They free range during the day. - I also have just about every chicken predator native to Texas. Hawks, owls, coyotes, foxes, possums, raccoons, feral dogs, etc. - I'd like to be able to go away for weekends without using an automatic door. - I'd like multiple entrances, as inevitably my roosters tend to pick on the smaller/newer chickens and keep them out of the coop until after dark. Hopefully multiple entrances will give the smaller chickens other options. I've thought about it for a while. I've decided that I need entrances to the coop that the chickens can get into, but none of their predators can. What kinds of entrances would those be? My idea right now: Entrances they fly up to, that can't be climbed up to. I'll place the whole coop on metal poles, so claws won't help climbing and they'll have no side of a coop to run up. The predators will have to leap straight up or fly. And I'm hoping that the owls won't be willing to enter the coop to get the chickens. So, to the help I need - I plan to eventually get larger breeds of chickens - perhaps even some of the giants. How high can they pretty easily fly when egg-heavy? 5 feet? Less? More? All of my lighter breeds can pretty easily make it 6 feet up, even the young ones. Second, can anyone see a flaw in my plan? Can any of those predators leap 5 or more feet straight up to the entrances I plan? Foxes? Raccoons? Will owls actually enter a coop, where they can't fly and pounce, and kill chickens inside the coop?
