You should contact your local agriculture extension office, or other similar officials in your area. Each area of a state can be different and often you don't if you have it in your soil until you keep turkeys and find out. Even than if you keep chickens and turkeys in separate areas I believe you don't need to worry.

Diagnostic Center for Population and Animal Health
Michigan State University
