I'm in need of some suggestions please- one of my buff orpington pullets, 24 weeks and not yet laying, suddenly droops her neck and seems barely able to lift it. She was puffed up unhappy 2 days ago with a turn of cold weather but otherwise normal. She gets flockraiser and plenty of water, grit, ashes to dust in, no oyster shell yet since they aren't laying yet. About 5 days ago I gave all of the chickens crawfish (family didn't like them and I figured I'd try it) and the shells of crab legs. That could be irrelevant since they ran from the crawfish;-) This morning her neck was like a goose neck- limply hanging although she walks around the coop. I felt for anything possibly stuck in the throat, clear. I felt all the neck bones and all are in line, no problems there. Neck IS very thin. Her crop is empty so she has not ate or even drank recently. Looked down her throat and saw nothing that shouldn't be. However there seems to be a small lump directly under the beak. When she makes noises of course it bulges so that may be a normal thing. I researched Newcastle, AI and the such but those don't fit because nothing else is 'paralyzed'. I couldn't get her to eat or drink but when put in the house of the isolation pen she jumps back out to be in the run. Any suggestions? I chose just 6 chickens to keep and now she goes wonky on me!
