I got a coop for Christmasand I'm ordering some chicks from Meyer's Hatchery for this spring (I live within driving distance, so it's sort of ideal for me.) My first question is, what exactly does the NPIP Certificate they offer for free entail? Is my flock considered NPIP-certified as long as I don't add any more birds, or is it just proof my chicks came from a certified hatchery? Two: do you think I should order any of the supplement packs they offer? Three: If I get the Meyer Meal Maker, can I get her vaccinated for Marek's like the other chicks? I don't want to pay for the others to be vaccinated just to have one unvaccinated bird in the flock. That's all the Meyer-related questions I have for now- if anyone can answer any of them, I would be really grateful.
