I posted a couple time. I had two girls both do the same thing. I went in the coop and my big girl was covered in blood. I was thinking that she was egg bound. I don't know what it is. It is under the vent looks like a big bloody ball. But it is under her vent and the skin looked like it was ripped on each side. My big girl did not make it. The 2nd on we Stiched Her up. She is eating and pooping well. I have her in a dog cage in house. I would like to know when she is healed can she go in coop with her sisters with no feathers on her backside. Thank you.
