Hi. My silkie hen (3.5 months old) goes into a sort of trance and lifts her head up slowly, drops it back down again and then raises it slowly again. She does this a lot. It's not like she's trying to hold her head up - she can do that fine. And she doesn't seem to be sick in any way. I'm wondering if she has some brain damage (maybe from being pecked in the head by my roo). She also sometimes stands facing the corner and will do that for ages. Has anyone else had their silkies do this?
