I hope someone can help us! The girls are 9 weeks old. They have been in the coop for 3. They were not roosting at night but were sleeping under their light. It has been cold here so we also added a space heater to warm it to the appropriate temp. At bedtime I would go out and add some fresh bedding to the spot under the light and while I sat there they would settle in. They looked comfy, not crowded . Sometimes one might use the other for a pillow! I had read on here that they would roost on their own when ready. I assumed they were not ready due to the cold and they just needed the light still. Well 3 nights ago I went out to put them to bed and they were stacked 3 deep(there are 11) in a corner of the coop. I was terrified they would suffocate. My one remaining bantam was, of course on the bottom. I did everything I could think of and they just kept going back to this spot. The last 2 nights the same thing, but I pick one up at a time and place them on the roost and say OK now PLEASE be a chicken tonight! Later I go back and peek in with a flash light and 8 of them are still roosting. Sound asleep and so cute! The remaining are piled on top of each other in the corner! I thought at first maybe they were to hot and trying to get away from the lamp, but they would be hotter sleeping on each other. Can anyone help? Am I going to have to put them on the roost every nite? Do they learn this or is there something that I am missing?
