I don't know but it is an interesting question. A biologist at Mississippi State told me years ago that if you did not shoot jakes that you couldn't kill enough mature gobblers to hurt a place. He said turkeys will find a way to die on their own. That's why some years you seem to have plenty of them and some years you don't seem to have any, even though it seems nothing has changed with the habitat. Just passing on what he said whether he is right or not I don't know... but on our place some yrs are better than others
