Hi everyone, I was wondering if anyone knew of a mareks disease vaccination that I could possibly buy online through a poultry or farm animal vaccination website? I am new to all of this, I have had my flock since the beginning of this past summer. Half of my flock was vaccinated for mareks disease when we got them as chicks, and half were not. I would like to vaccinate the chickens for mareks disease now so I know I have a fully vaccinated flock. I wish to do so because i would love to be able to let my silkie hatch out some chicks this summer, and i dont want the chicks to risk exposure/ i would like to vaccinate them once they hatch as well! I will not be able to do shots- I can only manage to vaccinate them with a drinking water administration technique, or a mist technique, because I am obviously not trained on how to use a needle! I have read online that there are water administered vaccines that are usable on older chickens, just cant find them! Any help would be great on this thank you!
