I am told that Turkey's are very susceptible to avian flu. Other states have had outbreaks in backyard poultry flocks, so don't be too confident you're safe. If you're in the flyway, practice good bio security and keep wild fowl separated from your flock. I would say that free ranging could be risky. I am only 14 miles from the Mississippi, and Stearns county had 2 outbreaks (again only 14 miles away) so figure I am in the hot zone. Not getting my birds this year though, got lots of work ahead of me preparing the coop, upgrading the paddock fence to be chicken safe and building enclosed runs.
