Hi, I just noticed a tumor (or something) on the back of the neck of a 2.5 month old orpington. I don't know anything about this. I certainly don't know what to do about it. I of course jump to the conclusion of mareks. (Isnt that what any chicken keeper would do? Jump to the worst possible conclusion?!) I took some pictures and Im asking for any ifo you may have about what it is and what I do about it.
Thanks!



Thanks!
