That's it for pictures, the large ball was attached to the backbone near the egg cell sac, it possibly could have been one of her kidneys. I had six bcm hens and I believe this one had never laid an egg. I believe her age to be 8-10 months. She had never shown any signs of illness until the day she died. My opinion is that that mass was growing inside her for several months, and putting pressure on her other organs causing them to shrink and eventually shutting down. Specifically her gizzard being extremely small.
