Found dead 5 week old poult in coop this morning. I decided to autopsy, and found that this poult's liver is spotted: I also found this fatty blob in a dead-end section of the colon (ceca?) and cut it in half: He was also pretty skinny, and his intestines were full of bile, which may indicate he hadn't been eating (?). I found this regarding blackhead: "Post-Mortem Observations The classical lesions associated with Histomoniasis are thickened cecal pouches containing yellowish, firm cores, and enlarged livers spotted with target-like lesions representing areas of necrosis, or cell death. While the gross lesions are usually diagnostic, it is important to confirm the diagnosis and rule out similar appearing diseases such as salmonellosis and coccidiosis. " But our liver has dark blotches, not light ones like in blackhead. I read this elsewhere: "Large blood clots in the abdomen or hemorrhage and hematoma on the liver are the result of trauma or fatty liver hemorrhage syndrome in chickens, or ruptured aorta in turkeys." Any one have anything to offer on this?
