Hey there BYC experts! We are just starting out and looking to purchase a few chicks. I noticed that some people post that the chicks are vaccinated for Mareks Disease and some do not. Is it necessary to look for chicks that are vaccinated? What if I get chicks that are not vaccinated? Are there other diseases that they should be vaccinated for? If I buy unvaccinated chicks, where would I go to get them vaccinated? Can I do it myself? OK, a ton of questions..... Any help is so appreciated!
