I have eight 7 week old hens, and they sleep in a variety of places in the coop. Three or four pile up together right at the opening to the run. Another one is over in the corner by herself, and two are often all the way up on the ledge. I put one of them on the roost, and she just stood there like "What do I do now??". They are so goofy and unpredictable. I"m still waiting for them to use the nice roosts that I installed. All that work and they aren't even interested yet!! Go figure.....
