I'm pretty new to smoking and I follow Jeff's recipes to a T. I smoked the maple turkey last year for Thanksgiving and everyone raved about it. This year I am smoking three 16-20 lb. turkeys in a Masterbuilt Digital Smoker. The question is how should I calculate time for three turkeys as opposed to one turkey. If one turkey takes about 6 hours, then will all three cook the same or should I count for extra time. I know it is different based on the size of the turkeys, but is it different for multiple turkey? Thanks for any help.
