Hello I have a three-month-old mixed breed from tractor supply. I came out this morning to find one of my favorites Indie leaning against one of the nesting boxes with her neck completely limp. She has no control over it whatsoever as if it’s broken but it doesn’t appear to be broken it just seems that way it. It was it was in the 80s yesterday and is in the 80s today. All other 10 chickens seem to be fine. She’s inside with me in a cool place and I’ve been giving her water via baby syringe (very little at a time). Any ideas on what to do or what it could be?
