I really want to get a few (2) silkies come next spring.(I will also be ordering other chicks of different breeds, at that time) I need to have chicks that are vaccinated for Marek's, as I have Marek's on my property. I order from My Pet Chicken, because I can get as few as 8 chicks, and they will be sexed as well. However, MPC does not vaccinate any bantams, including silkies, because they are too small. I know that Marek's vaccine needs to be administered at one day old, so that the chick has absolutley no exposure to the disease beforehand. I am wondering, if I order some silkie chicks, along with the other standard vaccinated chicks, and I order some Marek's vaccine, then vaccinate them as soon as I get them (they would be 2 - 3 days old), would that work?
