It sounds like your chick may be pulling through......I hope it is.....but I had 2 chicks behave like this which sadly didn't. I did everything I could, according to one of my books it sounds like "Newcastle Disease" Which you may call something different accross the pond. (I live in England) It's very common amongst little chicks, and there's not an awful lot you can do. The chicks behaved like yours, slowly deteriorating, it was totally heartbreaking, and they died after several hours. If yours is doing ok now, it should be fine. Twisting of the neck is a symptom of this. In England, for some unknown reason, it's been a bad year for chicks! Really hope your chick will be ok, I'm thinking about you! It's a sad fact but some little weaklings just aren't meant to be. Hopefully it sounds like yours is pulling through xxx
