I have a hen who became severely egg bound while I was out on Vacation last weekend. My house sitter was able to get the egg out intact (Friday eve), but my hen's behind is quite a mess. I came home on Sunday and helped her pass another egg (intact). I cleaned her up by soaking her behind as best I could. She had dried yolk and poop stuck to her vent/tissue, and she had a major prolapse with bleeding and what I would describe as hemorrhoids. I'm keeping her in a cage in a dark area with oyster shell and water to stop her from laying, but she is still prolapsed, even though I have pushed everything inside, and applied Preparation H (web site recommended for prolapse in chickens). My question is--can she recover from this, or do I need to cull her?
