With a family name of "Smoker" one would think that generations would have experienced this delightful process. Unfortunately not. I am just a newbie with a new Bradley given to me. Being practical, I see all those racks and space and want to fill it up. Not on the first time! But it does bring up the question .... if I was to do three chickens at one time, say about three pounds apiece with thermometer in one, am I figuring that the time to smoke will be more than for one but less than for 3x? Time I realize is not as important than temperature but would like some kind of quideline as to when to start process.
