The Hatcheries you refer to are not what I consider large Hatcheries. MSU here in Michigan is a large University and I have been there several times and they recommend Mareks Vaccine for all poultry. They do not recommend LT unless it is a problem. I told the Head man Dr. Fulton that I went to shows and he stated I should vaccinate. It still boils down to do what you believe works best for you.

Don, are you in Michigan? I am in SE Michigan. I've been following your posts with great interest.
