Wry neck can come in all sorts of varieties. This may be one of them. Give the chick vitamin E oil mixed in with some egg each day until the symptoms ease up. Use...

I agree, it appears to be a form of wry neck. It's not the sort of head shaking a chicken does when ears are hurting, but it would be a good idea to check in her ears to be sure there's no crusty material. Use a strong flashlight, and maybe a magnifying lens.
