For turkey, you can figure 30 minutes per pound. I did one last year, for Christmas. It was a 12-lb'er. I smoked it for 6 hours, and it was completely eaten. I didn't have any leftovers to bring home :(. This year for Thanksgiving, we got a 13.5-lb turkey in the freezer. I will start it in the smoker the night before, after I get off work (I work 3-11). That will be for lunch. Or I might start it Thanksgiving morning, for supper, when it gets done is when we will eat.
