So one of my 2 and half year old white leghorn hens has had a dirty bottom for a few days now. This is the worst I've ever seen and it seemed to be bothering her so I put her in an ice cream carton with warm water and Dawn and washed her off. She is very flighty and wouldn't let me do a very good job but got her dried off as best as possible then realized something was hanging from her feathers around the vent. Thought it was just dried poop so went to pull it off and with almost no effort it detached. It was some sort of bluish, pinkish tissue and had a couple drops of blood on it.
She is acting totally normal, eating, and drinking and running around like always. Don't think she has laid for a couple days but can't be sure as we have four other leghorns.
Anyone have any idea what this tissue could be from? And what should I do about it? Like I said, she doesn't like to be messed with.
Thanks for any help.
