I do whole chickens.
One of the benefits is that a whole chicken takes longer than individual pieces to cook so you get more smoke flavor... even though a whole chicken still cooks quickly. I run double smoke with my
AMNPS to get even more smoke flavor on the quick cook!
I smoke at 325F so the skin is edible. If you don't care about skin in your tacos I would suggest you remove the skin from the breast and thigh portions of the meat. This doesn't take long. I don't bother with the smaller more time consuming parts to remove skin from.
Finally, when I smoke whole chickens (and/or breast) I brine them with a simple salt and water brine. When done brining I season with Pepper, Onion, and Garlic for the smoke.
Finally, whole chicken is usually very inexpensive ($0.99/pound) so it works well for pulled chicken for tacos, soups, sandwiches, etc. I cook to 165F in the breast and about 8-10 pounds of whole chicken (2 birds) takes less than 4 hours at that temp.
Best of luck!
