LZZ,

Depending on the size of the bird, 3-4 hours is plenty of smoke. I always do mine with indirect smoke (cool, not cold) and they turn out great. I usually finish them covered in an oven at 350-375* for what ever time it takes to get the core up above ~170-180 for atleast 20 minutes. These guidelines have worked well for how we do ours. It will take quite a while in the oven, fyi.

They taste fantastic, but day 2 is even better once the smoke has really set in and all the oils permeate the entire bird.

Be sure that bad boy is defrosting in the fridge already!! Usually takes about 3 days to thaw. Remember, you don't thaw fowl on the countertop.
