Broody hen..Vaccinate chicks for Mereks?

[purpletree23]

I've always purchased my chicks from a hatchery and had them vaccinated for Mereks. I now have a broody hen who hopefully will hatch chicks. How do I prevent them from getting Mereks? Will I have to vaccinate them and where do I purchase the vaccine?

THAT is a very difficult proposition:

a) the chicks will hatch over a period of time.
b) they will be exposed to the broody mama as they hatch
c) they could get Marek's from dander in the coop
d) any vaccine that you get will only be active for one short hour.

I would only vaccinate my own chicks if the broody and the rest of the flock had been immunized.

Just an opinion...
