Actually I do feel like I am having some success with it. I broody hatched and raised 56 chicks last year, many within my "infected" flock and only lost 3 to Marek's. As I said in my last post, it seems to settle down a bit after the initial outbreak. Even if you cull the whole flock, the virus can remain in the grounds and buildings to re-infect new birds, so in my opinion, you are better keeping the survivors and breeding from them.
I understand the frustration of battling pests and predators and disease and I know how it feels when you think you are winning only for something else to crop up, especially when it is something major like Marek's. It's a heart breaking disease, but it is not as bad as much of the information you read about it and it would be a shame to cull birds that are healthy and may be resistant and could be bred from, only to replace them with new birds that could be less resistant.
