I have a little bantam hen that had a slight prolapse trying to lay her first egg. We pushed the tissue back in and applied preparation H. She laid a soft shelled egg after the first night. Some of the prolapsed tissue is slightly black from either pecking or frostbite. It's day three, and she continues to push it out with more coming out each time. It's not a lot, about a 1/2 inch, it started with millimeters. How long do I give her before deciding culling is the best? I don't think she will stop pushing it out, should I just leave her and see or put her down? She is sitting hunched in the crate where before she was relaxed. Has anyone experienced fixing this or will it be chronic? Thank you in advance for any insight.
