We call it a drunk chicken. Get a big-ass can of beer, take a big slurp out of it and replace the missing quantity of beer with herbs. Stick the can up the chicken's derrière and put standing upright on the bar-b-cue. Close the cover and let it sit there on medium-low heat for an hour to 1 1/2 hour depending on it's size. Why the beer? As the beer evaporates (especially the alcohol), it will tenderize the meat. At some point, the beer will begin to boil and kind of squirt the inside of the chicken too, kind of basting it from the inside. The herbs will come along for the ride and add to the taste.
