I noticed that one of my hens is not able to stand and her tail is flat but kind of puffed up. Her coloring is good and I do not see any obvious inflammation. I gave her an epsom bath in case of being egg bound, but could not palpate an egg externally. I don’t have any gloves so I cannot do an internal exam. She is interested in the slurry that I made for her but her head is shifting from side to side, similar to a neurological issue. Any ideas what might be happening and how I can help her?
