Our chicks will be coming in about 3 weeks. They are on order from a hatchery about 2 hours away. We are going to pick them up and not have them shipped. McMurray hatchery offers to vacinate the chicks against Mareck's disease and Coccidiosis. Is this something we should do, or should we just feed them the medicated feed? If we feed the medicated feed, does that replace both vaccinations or just one of them? Oh, the close we get, the more questions I have!!!! THANKS!!!
