I had a friend call me last night distraught that her favourite hen could barely stand up. She was cuddling Caramel, the hen, just the day before, but yesterday she kept tipping over to her left, walking splay-footed to support herself, but when examined showed no signs of lumps, broken bones, or wounds. Today she can only stand in brief bouts at best, otherwise she's laying on her left side, propping herself with her wing. She won't eat or drink. Does anyone know what this might be? It sounds like a stroke to me. The only diseases I can remember off the top of my head are Merek's and New Castle's, but the one I'm thinking of causes the bird to twist its neck around, and Caramel is not doing that.
