My birds are 15 weeks old and I usually let them free range in the afternoon and evening. They used to all go to the coop and fly up to the roost before dark and I would lock them in with no problems. Now they have quite the urge to roost in the trees in the yard! It was just the Golden Campines and Silver-spangled Hamburgs that made it up to nice roosting branches, but once the wyandottes and sussexes saw them they wanted up there too. I live in Alaska where there are many nighttime predators and the summers are short so I can't let them do this. How do I keep them out of the trees without clipping their wings???
