This isnt really a 'tip'...not one that gets the boss gobbler all the time anyway..more like an idea you can try.
I use dekes alot, two hens with a jake, they're designed to be simple standing dekes but with a little ingenuity i've made a shorter stake for one hen and set her lower in the grass with the jake directly behind the laying hen (right behind the hen).
Any dominant tom (or any adult bird for that matter) who busts out into the set-up will see the adolescent bird trying to breed the hen...that old boy wont like that, or the young gobbler, he'll try to run him off.
Thats when the safety comes off and i nestle the true-glo dots on his double chin...lol
