This summer we bought 22 pullets from a local, Wood County, Texas breeder. He claimed to be licensed. I isolated the birds for two months. After integrating these birds with my flock we began to lose the newer birds to Marek's. By this time the entire flock had been exposed to the disease. It has begun to affect my older birds now. I read that a herb, Hypericum Perforatum would cure birds infected with Marek's. After trying this I have determined that it is not effective. I reported the breeder to local health authorities. The course of action I have determined is to simply allow nature to run it's course. I do not think I will lose my entire flock but question whether surviving birds will be carriers of the disease. I would appreciate any knowledgeable advice.
