I was going to buy some chicks from someone on BYC, but their not vaccinated against Mareks or anything else. Does anyone vaccinate their chicks yourself ? Where do you get vaccine? What would you get ? or Should I not worry about it ? The 23 pullets I have were vaccinated for Mareks (5 hen I was told by the feed store they came from) and they all were fed mediacaed feed for cocci. I can give shots I'm a diabetic.Just need to know where on the chick and at what age. Thank you for your help.
