I have six 2 year old white leghorns. Last month we have had a few issues with what we believe is vent prolapse in one, then infections in a couple others. I have been applying monistat to all to clean up any infections. A week ago, one of the girls was bleeding from her vent, so I cleaned her up and treated her, and treated her each day. She seemed ok. They all seem ok now, but two days ago, one was acting strange, and I realized she has an egg that is stuck. I have been doing epson salt baths and applying vaseline trying to help her out, but nothing. I can't even feel the hole the egg can come out. Is it possible it grew over? She is trying and trying to lay, but nothing. I have her isolated now and dark towel over the crate. Is there anything else I can do for her?
