After trying several treatments on my five-year old Welsummer Molly, she continued to get worse, swollen, fluid-filled abdomen and very smelly sour crop, and she became so weak she could barely stand. So I euthanized her this morning and did a post mortem on her body. When I opened her body cavity, my suspicions of tumors were confirmed. I don't think I've ever seen such a "mother lode" of tumors, even in pictures in articles. My flock carries the LL avian virus, and occasionally one of them becomes symptomatic, and Molly's number came up. Here's what I found.
