My D brought in something similiar only it wasn't fuzzy yt (mold). Inside was a perfect egg. It looked like the reproductive tract came out with the egg still in it. It was just a white fleshy tissue, kind of the consistentcy of squid or some slimy fish flesh, no blood. These are new egg layers, 7 months old. By the time I got home, I couldnt tell which hen had laid the mess, they all looked fine. But I am assuming that she in now going to be eggless.
