imo I would take the drive ( we go to Meyer Hatchery in Polk though). You can get them Mereks vaccinated and they are much healthier coming from hatchery.
I haven't used that hatchery but I only get hatchery chicks.
You definitely have to quarantine them, I've read and heard for 4 wks. How much age difference will be between them?
Agreed, Merek's vaccinated chicks must not be exposed to older birds, or their dust/dander for at least 10 - 14 days, for the vaccine to be effective.
