I couldn't think of another way to describe this. This hen has been treated for coccidiosis recently and I separated her to the flock. When I tried to reintroduce her to the flock, they pecked at her and tore her comb partly off her head. They also pecked near her eye. This was about 2 weeks ago, and she seemed to move her head normally once she got used to the comb flopping around. I've put her in with the most submissive chicken so she wouldn't be lonely and so, I hope, I can reintroduce her to the flock. She's started laying her head over 90 degrees onto her shoulder in the most bizarre manner to look at me. When she's walking around pecking the ground she behaves normally, but it seems to be when something is taller than her that she does this weird thing. Basically she lays her head over on her shoulder, one eye to the shoulder and one eye up. Any ideas what's going on? She seems to feel well, eats and drinks and forages.
