Please tell me what you think. I just got 36 chicks from McMurray Hatchery last Sun. They were all vaccinated for Mareks & Coccidiosis. They are all doing fine. I have a friend who wants me to raise some chicks for her. She has difficulty tending to young chicks' needs. She wants to buy 10 chicks from a reputable local feed store and have me raise them with my other chicks When they're about 3-4 months old she'll take half of those grown chicks and let me keep the others. But these new chicks haven't been vaccinated. I had heard that it could be a problem, that the unvaccinated ones could catch the illness from the vaccinated ones. I don't want my friend's chicks to get sick, and I don't want to be caring for sick chicks. Raising them separately isn't an option, I have far too much else to do. Please let me know what you think about this. Thank you!
