Im glad you know about your hen and thanks for posting the necropsy results. From what I saw of Lorelei's organs, it was not Colibacillosis. There were no lesions on the heart and liver like you are supposed to see there. Naturally, I'm not a vet or a vet tech, but I read what I should see if she had many of the diseases people fear with their birds. If Lorelei had IB or MS, she was completely asymptomatic except for losing weight and not laying eggs. There wasn't so much as a sneeze from her the entire time. I just dont know. I'm not saying it definitely isn't that, but those are contagious. No one else is ill nor have they ever been. That puzzles me, if it was what your hen had. Rosie and Ruby seem fine now after the molasses flush and olive oil in their crops. I believe they may have eaten something they shouldnt have and/or the 11 grain scratch had some seeds in it that were mildly poisonous. I dont think it had anything to do with Lorelei, just too different.
***Just wanted to add that if one more hen goes the way of Lorelei, I am afraid I'm going to insist on a necropsy at the poultry lab. I do not relish cutting into my girls like that, no matter what the reason. Carla, what did they recommend you do with your flock? To hear some tell it, about 90% of the flocks in the U.S. already have MS/MG.
