Definitley not an expert but from what I have read most wild jakes in the spring are not mature enough to have viable sperm ! Some do they say but they seem to be the exception. I used to hunt in Montana around broadus area and I always saw lots of jakes and very few toms . I did see toms but they seemed few and far between. Then the next year I would go after seeing over a dozen jakes the previous year and think man should be lots of two year olds this spring and guess what ? I would see multiple jakes again ! Never did figure that one out !
