Sorry I should have explained.
I didn't have time to view the photos earlier but tagged Casportpony as someone who is very knowledgeable and can bring more people to discuss and try and give you answers.
I agree that looks like much too much fat. The gizzard also looks healthy to me except for the amount of fat. The lining of gizzards peel away quite nicely so they aren't full of that when eaten.
I agree there seems to be too many egg yolks mature inside her and possibly some yolk in other areas as well. While yolks are constantly maturing at different times I don't think there should be that many.
I too am going what is the black thing... was the black thing attached to anything?
