Sunday evening when I went to check and make sure that everyone was inside and ready to shut the coop up for the night, I looked in to make the head count. Saw a strange sight. My rooster, Buff, seemed like he was sitting taller than normal, I looked again and realized that he was sitting on top of 2 of the hens. They didn't seem to mind, were on the roost where he usually sits, and he had one foot on the back of each hen. I did make him move over next to them, and he was a little bit testy about it, but he did move. Has anyone else had any chickens sit on top of one another? Why would they do that?
