Thank you so much for the replies to my questions. I will be getting vaccinated chicks in the spring. I don't want to take any chances with my baby girls.
I have 2 questions about the mareks virus.
Question no. 1. If I already have adult chickens and I get chicks from a hatchery that are vaccinated for mareks, when I decide in the future to put the two groups together will the vaccinated ones expose the older ones to the mareks virus...
