Can someone please help identify this? One of my hens had a really poopy butt which I washed and found this dangling from the vent area- is this a prolapsed vent, or dried up part of an egg that she did not manage to lay completely? It is gelatinous looking, and I did not dare scrape too hard in case it is part of her anatomy and I end up injuring her. I tried pushing the whole thing back into her vent last night, but it returned again today. Any suggestions would be appreciated. Bella is going on 5 years old and has a lovely personality and still gives the occasional egg. Thanks.
