Like with anything in nature. The strong survive.
There have been times both my partner and I decided we'd take a Jake only to tough it out and end up with a 2 yr old or better.

On that flock I hunted Jan 6
13 were long beards. They entered the field long after the hens entered.
I saw 3 flocks of jakes from 3 to 4 to one group of 9 and a group of 6.
I quit counting after 70 with hens. I just couldn't keep up.
The hens fed in groups. I'm willing to bet it was a family type gathering. They were from the same clutch.

i really try to pay attention to what i see then try to mimic that setting with a decoy or decoys!

But how to manage your flock.
I'd plant turkey specific food plots.
I don't believe that under fair chase one can decimate all the mature Toms through hunting.

It takes a year and a half before a hen can lay eggs.
