Have a 10-12 week old rhode island pullet who up until a few days ago seemed to be fine, running around with all 35 of her pals and eating well. Recently she went into an episode where she pulls her head as far left as she can and she has difficulty walking. It almost looks as if she's had a stroke or way too much booze. She initially was able to walk (in circles) and eat/drink. I figured she'd be alright but the next day she deteriorated and was unable to eat or drink. She has her perching reflex in both feet. She initially squawked when I'd straighten her head out but no longer is able to. Sometimes she would give the faintest sound but even that is gone now. All she does now is lay on her side and occasionally move her head up and down. I'm not sure whats going on with her so I will probably be culling her when I get home from work unless she somehow finds a way to improve. She is separate from the rest of her flock with plenty of fresh food and water. The other 34 hens and the duck show no signs of distress and are doing well. Does anyone have any idea what could be going on with my hen? Thanks in advance!
