We had 2 Dutch pullets die from what we believe was Marek's Disease early last year. We've since hatched chicks in an incubator and vaccinated them for Marek's and kept them away from the infected coops for a couple of weeks so they should be protected from the disease. My question is: Since these chicks, which were vaccinated, were returned to the old coops can they now be carriers of Marek's even though they won't get it? We recently moved one of these pullets to another area and hatched 5 chicks under her and we want to vaccinate these chicks but now I am concerned that the mother may be a carrier and may have already infected them so vaccination may be useless.

Marek's disease is complex. Vaccines don't prevent it, just lessen its severity and render it less contagious. I've heard more than one source say most birds have been exposed just by existing. I have had chickens vaccinated and still die from the disease. As such I don't vaccinate, prefering to breed for resistence.
