Boy, this is a rough day.
Cyn, she didn't look like the pics you had posted when the oviduct was a hardened mass. She had almost no developing yolks, but tons of fatty material in her oviduct. There's no way anything could have gotten through there, but nothing was developing anyway. (Maybe because of the molt.) Her liver looked good. There was a tiny, tiny spot on one lobe of it. I will ask the vet later. I'm pretty puzzled. As for the oviduct, was it just normal fat, or was it a fatty tumor? I probably should have sent her off for an official necropsy, but right now, I'm just wanting her buried.
ETA -- she is buried. rest in peace.
