Hi all! Last week we hatched out 3 healthy chicks from a homemade incubator. They are a week old as of today. Only today did I remember about vaccinations. Marek's, in particular. A horrible newbie mistake, I guess. We have 3 older pullets outside, who were hatchery vaccinated when we got them. Everywhere I look recommends vaccinating chicks within 24 hours, and a lot say it is completely ineffective if done later. I'm looking for opinions on how effective a vaccination at 1 week would be? Either way we will be getting the vaccine from our feed store to vaccinate them ourselves tomorrow, but I'd like a heads up to know how much it is really helping. Would a follow up increase immunity chances? A slightly bigger dose? I'd love some advice from you guys!
