Greetings Smokers, I am looking to do a smoke for the office. Using a gas grill with a smoker box to do a smoked beer can chicken(s). How many chickens do you all think it will take to feed 18 people (5 females and 13 males; 9 civilians and 9 Marines)? I was thinking 4 Purdue Oven Stuffers should do the trick. Thanks in advance.
