At what age do chickens start to use their roost? Mine are 12 weeks and still seem to sleep by snuggling together in the corner of the coop, in a deep pile of litter. Is that normal? Will they start using the roost at some point? They do get on it frequently during the day, I can tell b/c it's covered in droppings every time I go to clean up. So I know they have no problem at all hopping up there. Maybe it's just warmer down below?
