VACCINATION OF CHICKS

[Justturkey]

I have 1 week old chicks that have not been vaccinated for Marek's disease. Can i still do that?

You can but it is much less effective after day old and loses effectiveness by the hour. After hatch, the vaccine is in a race with that in the environment and that is everywhere.
I wouldn't worry about it unless you have a history of Marek's in your area. Some chickens are naturally immune. I never vaccinate.
