I apologize if anyone is grossed out by this, but I figured I needed to post the picture in order to depict what I'm talking about. We butchered a few hens today and one of them seemed very plump. I was nervous cutting into her because she seemed filled with fluid. That she was! The fluid that came spilling out was not blood, cloudy or smelly - just kind of gray-ish as I recall (it surprised me). Next I found a huge brain-like mass. She did still have some undeveloped eggs in her (none that were developING though). I have a picture, but it's kind of gross. The mass was very firm and gray, about equal in size as her other viscera. She never did seem to feel poorly - she was just older and we are culling. Any insight? Thanks!
