I never thought I would see myself posting this.... But unfortunately, Cyn, I lost one of my hens to what I believe to be this. We necropsied her and there were small bumps/tumors all over the place. It smelled of rotten eggs with yellow liquid in her body cavity. There were even, what seemed to be, egg yolks attached inside. My dad let them out this morning around 8 and she was dead in a couple hours. She was a Rhode Island/Production Red from Ideal, and lived to be about 2 1/2 years old.
