Help with necropsy photos?

I had a chicken that had signs of Marek's disease. Over the span of 2 weeks she went from good appetite and one paralyzed leg to both legs acting paralyzed and barely able to function. By the end of 2 weeks she flopped around helplessly. She tried to eat, but could barely manage a couple of pecks at her food. We culled her today and I did a quick field necropsy with a dull knife. I have a couple questions about what I saw and attached some photos here. There was a bright green fluid - is that normal? There was a large structure, donut shaped, in her belly. I cut it, and it was a uniform tissue. What was that? Do her follicles look ok? I probably didn't find any diagnostic features of Marek's, but I'd sure like another opinion.

I don't know the answers to your questions...but I wanted to offer a suggestion. I had a hen who died this spring after being sick from salpingitis. Hubby and I did a necropsy on her and filmed it, took pictures, etc. I sent the video and pictures to one of the professors at University of Arkansas who works with poultry. He was gracious enough to look over my pictures and video and give me a good diagnosis (salpingitis) of what killed my girl. You might want to try this option? You could either try U of A or one of the many other colleges that specialize in Animal Science...

Thank you. It's too late to make a video for this chicken, but maybe I will if more die. Looking at more photos, I'm pretty sure the donut shaped organ was the gizzard - it just wasn't where I expected it to be.

Lots of really smart people on here. I'm sure they will comment soon....

But in the meantime, this is a free online course about chickens. There is a necropsy video in the course that might be helpful. I watched it several times before doing my own necropsy on my girl.

Sorry for your loss. I am not that experienced with knowing what I am looking at in necropsies. The second picture with the green looks like there could be small tumors or infection in the mucosa, and the green color must be bile. Did you nick the gallbladder by any chance? If not, I don’t know what might have caused that. How did the liver look to you . Did it have any spots?

The liver looked super clean to me. I believe I must have nicked the gallbladder, though I didn't notice when I did. It was amazingly bright green I must say.
