Our two and half mo. old chickens don't want to go to bed at night. We've got the coop light on, I've moved there food and water back inside the coop but they still huddle up in a corner and I guess bed down for the night. Makes it easier to put them back in the coop. And there,, well most of them are all sleeping together in the nesting boxes! Are they to young to roost? I think if I left them out there they'd be fine with it. In the mornings when I do the water and food thang and open the coop to run door. They have no problem going from coop to run and it's a really nice coop.
