Hello everyone, I was shopping online at McMurray Hatchery and all of their 4 week old chicks have been vaccinated fo Bronchitits, Mareks, Coccidiosis, and Newcastle My current flock of 4 silkies have recieved no vaccinations. My question is are any of these vaccinations ones that will shed the virus and infect unvaccinated birds? What other vaccinations are harmful to unvaccinated chickens? Thank you in advance!
Mixing vaccinated chickens with unvaccinated.
Vaccinated chicks will not cause your non-vaccinated birds to get sick. If you have birds that have had some sort of infectious disease, however, it is very dangerous to introduce birds that have not had the disease, or are not vaccinated against it.
Chicks that have been vaccinated for coccidiosis should not be fed medicated feed, though.
