I have a silkie hen that I originally thought was just blind (after trimming around eyes). She has always backed her way into a corner. I have kept her with her friend who seems to assist her in getting to the food and water. She sleeps on the ground, and as of today isn't using her legs, but instead flaps around and sits on her bottom. I have checked for mites, she doesn't hold her head up very long, but doesn't appear to be wry neck. (I seriously thought she was just stressed when I got her.) Please help!
