Since I am finally starting my Oriental gamefowl project in December, I wanted to go ahead and get as many ducks in a row as I can. One of these ducks is about vaccinations for Orientals. Do you recommend that I vaccinate them at all, or should I breed for unassisted resistance? How often should I vaccinate adults, and from what diseases should I vaccinate them? I know that Marek's is responsible for claiming a lot of backyard birds, but didn't know if it was as common among Oriental gamefowl. Lastly, is it safe to vaccinate an adult Oriental against Marek's? The cock I'm getting in December is fully grown and has been given deworming medication about twice, but has never been vaccinated against Marek's. Since he is as old as he is and has not contracted the disease yet, should I just assume he has good immunity and not vaccinate him? Please give me your experience about these things. I plan on free-ranging my Orientals (with some restraint due to gamey males), so they will be exposed to the germs that come with free ranging and won't spend a pampered life in a cage. Thanks.
