Anyway, I know Mereks is a problem in some places but I find Cocci to be a much bigger problem. As an aside, we have neighbors with Turkeys. I've heard that Turkeys can be great to keep as they carry something that protects the chickens from Mareks.
Turkeys carry Marek's Disease Virus serotype 3 aka HVT. It has no effect on turkeys. The initial Marek's vaccine was made from HVT as HVT would produce antigens for the initial chicken strain of MDV. Think cowpox and smallpox.
