Sommer, I understand your feeling about giving them the vaccination bazooka. I've considered it myself, many times. It is hard to decide between wanting the flock to be naturally healthy or, in some cases, just alive! I'm getting my flock NPIP tested this coming week, as long as the weather cooperates. I was all set to give them the Marek's vaccination, also, but now I'm hesitating and going to go back to do my research again before I make a final decision. It's just complicated. I think when they don't have fresh grass under their feet, and mine have the opportunity but prefer to stay closer to the coop where they've worn it away, it becomes more important to guard against illness. Decisions, decisions.
