If you have a gas grill have one side of the grill turned on and the other off. Place the ribs on the side that is turned off and close the barbeque. This allows the heat to circulate and cook your ribs without burning them. If you are using a charcoal barbeque separate the coals to both sides of the barbeque and none in the middle. Place the chicken in the center of the grill and put the top on the barbeque. Seriously consider using smoke wood chips when making this chicken for added flavor.
