I’ve been hunting turkeys on our land in south central MN for 5 years now. The first bird I shot had 1 3/8″ spurs, no idea on age (11 3/8″ beard, 25-26lbs). Second bird was a jake, so age 1. Bird last year had 9/8″ spurs and was one of two jakes I watched on camera all fall-winter-spring, so age 2.
With little reading, and more hearing, I was under the assumption that spurs were fairly age dependent. With everything in nature though, I would presume that factors such as genetics, competition, nutrition, etc. play roles in variable degrees of importance.
Heres to hopefully your first 1″ plus spurs someday blowing past that mark – Good Luck
