Sorry for the loss of your hen. How old? The report didn't mention eggs, so had she stopped laying? They are doing further testing for Marek's and leucosis, so a further report will be helpful too. Fatty liver with hemorrhage is not rare in backyard birds, especially if she was no longer laying eggs. Lots of high calorie goodies, less exercise, and genetics. Sounds like checking for an overabundance of coccidia, and maybe treating the flock, is indicated. She may have been the bird who was in failing health so the coccidia took over. Having a necropsy done is really good, because you will get answers, and can make informed decisions as you move forward. Mary
