So, I bought four olive eggers all of laying age from someone. Kept them in the coop for a few days when I first got them, then set them to free range with my others. That night, only one of the four returned to the coop for bed and I couldn't get them to go inside. I called the lady I bought them from to see if she had a special call or something. She informed me that those hens did not go to a coop at night. "Sorry,"she said. My problem is I have an overgrown area across the way from the coop and at night these hens just fly up to a tree branch for the night. They know where the coop is because they go in to lay eggs. What about when winter comes? I also worry about predators-though they are roosting up pretty high in the tree. Can I re-train them somehow? I ran them out of the tree the first night, but they would not go in the coop for anything.
