I was inquiring about some chicks from someone on craigslist. It's mosquito season bad and most of my flock has already gotten or still has signs of pox so I've been nervous about bringing new babies in unless they have been vaccinated. I asked this person if their chicks had been vaccinated against anything so I know if I have to buy the vaccines or not. They said the chicks parents were vaccinated so the chicks didn't need to be. Is that true? Am I still going to have to vaccinate them for pox at 5 weeks?
