Birdman, If you lift the skin on the breast and take some butter and rub under the skin, it will keep it moist. I smoked a chicken yesterday (beer can) and I injected it with a mixture of butter, salt, pepper and some cajum spices. When I cut into the breast, the injection liquid just ran out and it was one of the most moist chickens I have cooked. caveman also suggested to put strips of bacon across the breast and I can say that also works, however I prefer to inject. I used to brine all my chickens, but I don't find there is any advantage when you inject. Just my opinion.
