Hi there, a couple days ago I noticed that my year old chicken's butt became swollen, red and bloody. It looks like part of her stomach is coming out of her butt. Also, she's been pooping yellow goo. She's the lowest on the pecking order due to her legs being sprained, I don't know if that's relevant. Please help cause she looks like shes in so much pain and she screams occasionally.. I put her in a cage alone away from the other hens and I put water and feed.
