I wondered that SAME thing, Lacy! Mareks, I heard, was horrible this year. But more than likely, there were some that made it through exposure and weren't even affected - would those not be the ones that you'd want to use when breeding for resistance? That must have been one strong bird to live through Mareks - it's a horrible disease to be sure. Darn wild birds!
The ones that are exposed & don't develop symptoms are, in fact, the ones to use when trying to breed for resistance. The ones that are symptomatic & recover are forever carriers & will ensure that you will have more birds with Marek 's. They are definately not valuable as breeders.
