I found one of my chickens, Brown Leghorn, a young pullet, dead last night. There had been no signs of distress, she looked healthy before, with red comb and wattles. I opened her up this morning and discovered that she had an enlarged, yellowish liver, her other organs looked pretty abnormal as well. We happened to have slaughtered 4 other chickens, a couple of extra roosters from laying breeds and a couple of broiler hens, a day before, and they were all perfectly normal, with normal livers and other organs. Below are a few pictures from my autopsy. I hope someone is familiar with this issue. I don't know if it's anything I should be worried about in my other chickens.
