My Barred Rock has recently (6 days ago) started a new, and undesirable, habit of attempting to roost in a tree at night. It's the same tree every night, just outside their fence. Our flock is 7 guineas and three chickens, they've lived together in relative harmony for almost two months now. I saw relatively because the chickens don't really seem socialize with the guineas much. I can't say that I blame them, the guineas are terribly loud and obnoxious. During the day the chickens are free to come and go from their fenced area, all three would return to their house around dusk and were on their perches before the guineas. Last weekend however, this little chicken decided she was going to roost in this tree (we didn't realize that's where she was the first night, we thought something had run off with her) every night. The other two go back to the house, and she gets up in her tree about 12 feet off the ground. I've tried telling her that it's just not safe to sleep up in trees at night, regardless of what she might hear the wild birds saying during the day. She doesn't listen. Every night we have to scoop (we use a very long stick, press it under her belly so she'll step onto it, then lower her down) her out of the tree and put her in the coop with the rest of the flock. We're not going to let her roost in the tree, there are far too many creatures out here who would love a tasty chicken treat. Any guess what would make her want to roost in the tree alone at night all of a sudden? Other than scooping her out of the tree every night, any suggestions on how we can get her to go back into the house on her own? There are plenty of roosts available in the house, there's a whole unused side of the house if she doesn't want to roost with the guineas. Thanks!
