I keep reading how when chicks are vaccinated, they then need to be quarantined for 2 weeks, so that they don't get exposed to the virus before the vaccine takes effect.
How does one do this in practical terms? My chicks hatch under a broody mom, who raises them. Even if I take broody and her eggs and bring into a clean box inside the house while they hatch and until they're 2 weeks old, the chciks still are exposed right? Because I have to assume that mom has the virus on her skin, dander, and feathers, so she would immediately be infecting the chicks.
Even if I culled my whole flock (not gonna happen, just theoretical question here), as I brought in vaccinated, quarantined new chicks, they would then pick up the virus from our soil, air, coop, etc and become carriers. then the next time I try to have a "new", vaccinated hen hatch out chicks, they would again be infected by their mom, who would have it all over her body even though she's vaccinated. Almost seems like I just have to count on many chicks dying if I do indeed have Marek's. What am I missing?
