I just put my chickens to bed and saw that one was on the ground. I put her back up on the roost. I did some research and she could be sleeping on the ground because the coop is dirty (which mine is; it hasnt been cleaned in two weeks, yes I know SUPER dirty I will clean it tomorrow ) Is this the case? Could their be any other reasons for sleeping on the ground? It could also be could but I dont think so. Any thoughts?
