Just found my 4wk old columbian wyandotte chick with her head and neck tucked way down in a separate corner of the brooder. I noticed yesterday that she very oddly ran backwards for quite a few steps with her head tucked under. I just thought it was an oddity. She is the chick that I posted on the other day but never got any responses. She is not really feathering out and has bald spots. I've tried research and found crook/wry neck but I'm still not sure I understand if that's it. She's on medicated feed. It's 9:30 at night right now and I have no way to get anything from a store til morning. What do I do??
