When I went out to gather eggs today my EE is bleeding from around her vent. It's hard to tell where it is coming from though she obviously layed her egg after it happened as there was a little blood on the shell. She is at the bottom of the pecking order and we have had issues with the other girls pucking out her tail feathers and pecking at her bloody bottom before. We treated her with blu kote and haven't had any problems sent. I have never seen it as bad as it is now. Is it possible one of the other hens did it or is it something else? This is my first flock of chickens so I don't even have a good guess. I took a picture but I can't figure out how to post it. I would appreciate any help. Thanks!
