I haven't read a thread about this question, so thought I'd ask. I was thinking about the predator problem. I live right in town, but we've seen raccoons and skunks around, and I know there are mice. I know about chickens only what I've studied in the past 5 days, so advice is welcome! I'm thinking of creating a roost bar on supports hanging down from the ceiling so that nothing else touches it -- no connections to the walls or wood pieces underneath for something to climb across or up. I'm also thinking "the higher the better" to be away from any creatures on the ground. Does anyone have a roost bar that is 5 or more feet off the ground? And... do the chickens have a problem getting up there?
