The pic [@=/u/297297/duluthralphie]@duluthralphie[/@] posted is most definitely not an illness of any kind...unless you consider hormones an illness. That is what happens when turkeys fight. They will literally pick each other's heads bloody if several gang up on 1. That is the result of toms fighting for dominance.
It took me a while to realize this, I was researching blackhead, Fowl pox, Frostbite, Scurvy and anything else I could think of that caused this. Then it dawned on me it goes away quickly and then reappears in another Jake. I have noticed it has tapered off now, I think they are getting an order figured out. I assume when 3 of them move away or go to freezer camp the fight will start al over...
