We lost a 6 month old Polish last night and today we opened her up and found tumors. I know AL and Mareks have tumors but is there a way to tell which she has without a test?

Did your chicken ever show any lameness or paralysis? Both Mareks and lymphoid leukosis can cause tumors on the liver and many other organs. Mareks causes tumors on the nerves and can cause tumors on the skin and the eyes. Leukosis does not cause nerve, skin, or eye tumors. Mareks disease strikes about the age of 2 months and older. Chickens with leukosis may get symptoms at 4 months and older. To get a proper diagnosis, you probably would need to have the state poultry pathologist to examine the tissue. Sorry for your loss.

No symptoms like leg issues. Yesterday I found her head first in a corner. Put her in a warm area and she kept shaking her head and breathing hard. Last year we did have a Marecks positive flock but they all passed. We cleaned and got a few birds to see if we could rebuild a flock.

Well, then I would guess that it might be Mareks, since the disease can remain in the environment in feather dust and dander for months to years. Here is a lab in Texas that can do a $20 blood serum test for Mareks, if you have another bird who might have it. Sorry that you are dealing with this terrible disease.

That’s who did my first diagnosis. RAL. It’s a horrible disease. I suspect the other few will get it too.

I also got about 6 chickens last year from a breeder who had an outbreak of Leukosis so I wasn’t sure if that stayed around in the ground. We did clean the coop with Oxine I believe it was called.
