I wasn't sure what was happening with my one hen at first. I knew she had a mass inside her abdomen. But I wasn't sure what the mass was instill today. Today I decided to brave it out and find out what was going on inside her. I got my things together to do the surgery, sterilized things, and made a two inch cut below her vent ( not her actual vent ). I got inside and found the mass without searching. What I found was a mass of egg yolks about the size of a baseball. I removed the mass and stitched her up. She is now resting in a pet taxie. I have put antibiotics in her water. I will post pics soon. I was just wondering if anyone else has ever tried this?
