I have 5 buffs and 2 rhode islands. We have two roosting spots in the coop. Every night, I only have 2 or 3 chickens (rarely 4) roosting at night. 4 of them normally just sleep on the ground....just wondering...if it was normal. I'm not all that concerned becuase they seem to be happy and healthy. They just seem to prefer the floor to the roosts.
