i had a tractor supply coop that we boarded up so it was one big coop. It is inside a large 10, x 10, run. Before we boarded the coop, the chickens slept inside . Now around 5-5:30 I see one of the roosters making sure they all go inside. But when I went outside around 9:30 at night, they were all fast asleep on the roof of the coop. Should they sleep inside? It was in the low 20’s last week.they look good tho. I will add pictures of the outside soon.
