I have a silkie hen that I've noticed acting funny. Several times I have caught her inside the coop, facing into one corner of her coop, against the walls, hopping up and down like she is stuck looking for a way out. I picked her up and checked her eyes, etc. to see if she was blind or had a noticeable infection of some kind. She appears to be perfectly healthy. I moved her several times away from that corner and she went back to it every time and continued the behavior. She doesn't do it 24/7 but I have seen her do it on more than one occasion. It reminds me of an obsessive compulsive disorder, like a dog that has gone kennel crazy. Does anyone have experience with this?
