Solution: Avoid raising turkeys on ground previously used by chickens or where chickens currently range.
Explanation: Blackhead is caused by a protozoan often carried by cecal worms, common in chickens (which are usually less affected). Turkeys are highly susceptible. Prevention involves strict separation from chickens and their manure, rotating pasture, and good sanitation.
Notes: There is no effective treatment once symptoms appear; prevention is paramount. Symptoms include lethargy and yellow droppings.
