background: I acquired about 40 chickens three days ago, about half are roosters. Adults. They are currently in a run in the barn that is too small for them, so yes they are crowded (that will be rectified this weekend). One of the roosters keeps putting his face in a corner of the run or in a corner of a box and he puts his head down, butt up and just sits there. no one seems to be picking on him when he does this. Any ideas why? Is it likely just stress from being crowded, or indicate some health issue? He does have scaly leg mites, but otherwise seems okay.
