A lot of people are vaccinating for Marek's. Many breeders I have talked to started vaccinating because clients wanted them vaccinated. I've purchased eggs, chicks and pullets from craigslist and most transactions have gone very smoothly. I did pay quite a bit of money for some legbars that ended up being infertile and the rooster is not pure like he was advertised. We culled him anyway because he was aggressive. Other than that all the chicks have been healthy.I was just about to mention Craigslist, I was interested in blueish chickens and found several there. I was wondering if there is anything to worry about with craigslist chicks? A few of them claim they are vaccinated for mareks.
