I am possibly picking up 2 BOs and a Polish chick today ( all are about 4 weeks old).I have 5 other 3.5 month old chicks who are Merek's vaccinated. These new chick aren't vaccinated and I wonder if this is something I should worry about. I really want my BOs and have really wanted a golden laced Polish for about a month (even since I saw one!) How prevalent is Merek's disease in the New England area? I know many of you don't vaccinate and many do. So both views are valid here.
