We had a couple sleep in a tree one night. My neighbor had given me three pullets, and they were used to taking care of themselves. Unfortunately they were the last 3 of a larger flock that was picked off by preditors. She gave up and gave them to me since I have a coop. One night two of them perched in the tree and just wouldn't come down. I finally gave up. They looked very peaceful and happy, but I was sooooo nervous for them. They were ok the next morning, but they prefer the barn now, which helps me sleep better, lol! Oh, one of them is a brown leghorn, but I'm not sure what the other one is. The third one she gave me is a nice Langshan, but she's not such a rebel!
