My hen Peach was with the other hens today in the corner eith the bikes, but when I went over she was the only one not moving, I checked and saw that she's been wounded from over breeding. She has a big tear in her skin, it doesn't seem infected and there's no blood. How do I heal this? I can keep her seperated in her own cage if I have to. I'm also putting down one of my two roosters right after I comment this.
