They are 3 months old and they wont go in their coop at night. When the meat birds were with them they would all go in when it got dark. Now they started sitting on the fence rail and going to sleep, so I had to carry them into the coop every night. I removed the fence rail and raised their coop perch up to the window. So last night I didnt see them so I went to shut the coop door and only one was in there the other 3 were in the freaking tree. I could barely reach the Silver Leghorn Roo. I could just let them stay out there, but we have raccoons, coyote, and etc. They also prefer to sleep huddled together in the corner of the coop on the floor rather than on a roost.
