Hello, My barred rock has a strange, reoccurring, but rare condition that I don't understand. Every once in a while she starts moving her head like she has a crick in the neck. That's the best I can explain it- she'll stretch her neck and head, lifting up the neck feathers, and shuddering all the while. It looks very uncomfortable, and when she's trying to adjust she won't eat or drink. I can't gauge exactly how long this lasts for- anywhere between a few hours and a few days. I figure she either works it out, or gives up. I don't watch her 24/7, but am worried when she doesn't eat or drink, obviously. Has anyone ever seen anything like this?
