I'm guessing that you are feeding a high protien turkey or broiler ration. The toms eat more and grow faster due to a higher matabolism. But all of that energy has to be released somehow. Think of the labored breathing of an overwieght person after a heavy meal, to much un-needed energy. Try feeding twice a day and only what they will clean up in fifteen minutes.
You might also try broiler booster from Mcmurray hatchery. It really helps my heavier birds turn energy into growth and reduces stress.

cpp, thanks for your response, it makes perfect sense. We will cut back on their feed consumption. Tonight we let them out of their turkey yard to free range in our back yard, they move really slow due to their large size. I think it will do them good to slow their growth down a bit.

Thanks,
