I was originally going to smoke one and fry one but now am considering smoking both, at once. What should I expect differently from my first cook with a single 12lb bird? Are the temps gonna be a lot harder to bring up? I have a dual probe thermometer and wondering where I should place probes. Should grate at the bottom get one? I don't wanna get in over my head on on thanksgiving day but I think the result is worth it to try.
