I have two Narragansett turkey toms that are about 8-9 months old and they have some kind of disease. They had symptoms several months ago for a while, then they went away. I havent been able to find any ill effects other than the stuff on their head. They dont seem to have any respiratory problems or health issues, they still eat regularly and they get around in the yard with no obvious issues. In fact, other than the darkness on their head cant find anything else wrong with them. Still I wonder what it is. This has come on in the last 3-5 days and has gotten worse. It was about this bad before. I see no swelling on the head or any where else. Only these 2 toms have it. They live in a coop with 9 other turkeys, about the same age, and all of which came from the same hatchery at the same time. Also in the coop are 10 chickens and 2 geese. And before anyone gets upset about turkeys and chickens together, I have had my chickens and turkeys together for the past 4 years and have had no problems at all. And to the best of my knowledge, these symptoms are not consistent with Black Head disease.
