A little over a year ago, I got 3 silkie chicks from Lancaster Fancy Fowl. Two of them died when they were chicks and my favorite chicken, Remi is the only one who made it but she's always been a little smaller than my others. She's been mostly laying in the coop during the day for the past week, but I didn't think anything of it until yesterday when I noticed her not being able to walk straight and her neck looks like someone broke it. It's like she cant balance and she can't hold her head up so she keeps it tucked under herself. She also has been trying her best to eat and drink but she has no coordination or aim and can't manage to get feed by herself. When I pick her up her neck just hangs down like a rag doll. Anyone have an idea of what's wrong with her, and is it fixable??
