My 5 year old Orpington, Lucy was wobbling five days ago and could barely walk. She mostly laid under a bush and I thought for sure she would be gone by morning. She was my very first chicken so I was hoping her death would at least be painless. She made it into the coop on her own that night and squeezed into a box with another hen, for added warmth I assumed. She was still in the box in the morning, so I left her some food right in the box. I was surprised to see her out, but still wobbling later that day. This went on for several days. Now, five days later she walking around and eating and drinking and seems just fine. I’m thrilled she’s doing well but would love to know what could have happened to her to cause her semi paralysis. I’m now adding vitamin supplements to the water, mainly for her, but everyone gets it. Incidentally, I have twelve birds total and none of the others had similar symptoms. Attached are a few pics of her from today. You can see she’s up and about.
