It will not effect them at all. Like me, tom's are horny all the time but it is the timing of the hens wanting to nest that will determine when the mating process starts. Contact your Game & Parks Biologist and I'm sure they've studies the averages of when the hens start nesting in your area. I've never seen toms burnout in the beginning of the season but have heard of them shutting down at the end of the season in mid-late May.
