Look at Avian Leukosis (sometimes called 'big liver disease). It can look a bit like mareks disease but results in an enlarged liver, sometimes with lesions. You can get involvement with other organs and often the spleen.

There's no treatment for it, and the disease can be transmitted through the egg vertically.

You never want to freeze any animal you will be submitting for necropsy. Freezing damages the tissues and may prevent a diagnoses. If you can't get the body in within a few hours of death, then you will want to refrigerate it immediately and submit it ASAP.

for maggots not inside look here: http://www.worldpoultry.net/diseases/botulism-d93.html Plus this a copy from it.


Postmortem lesions
Few to no gross lesions are seen. Maggots can be seen in the upper digestive tract.

The maggots are not the result of Botulism, but the result of hatched fly eggs being in the intestine. Most dead animals wind up with files getting quickly into them. I dispatched a porcupine inside of 24 hours there were files coming out of it, in 72 hours the carcass appeared to be moving and there were maggots coming out of it all over it's body.
