Im not sure about turkeys but I know that people rarely vaccinate their ducks . Unless you plan to take them to shows than its unnecessary for ducks because they are very hardy. A lot of people vaccinate their chickens for the main viruses like mareks, new castle, bronchitis, fowl pox and a few others. Mareks is very easy to vaccinate for because its only once and its usually done on 1 day olds at the hatchery. It mostly depends on your area and wether their have been poultry virus outbreaks. You can contact your state extension and ask what they recommend you vaccinate for in your area.
