AV is NPIP, (I don't think Galore has that designation) and they may be hatching some varieties on site, but not what I purchased the last two times round. Do you incubate? If so, I could help you out with where to get some good eggs for hatching, and whom to avoid. I am so sorry to hear about the Mareks on your property. Chickens Galore used to state on their advertising that their chicks were both vaccinated and on medicated feed. As far as I know, the one negates the other and that was a red flag to me, indicating that they did not exactly know what they were doing.
