My favorite way to get juicy barbecued chicken is to put beer in the cavity during cooking, and you can do that a few ways. You can buy a fancy contraption that will hold a can of beer inside the bird while it cooks upright or you can balance the bird on the beer can yourself. Or you can do as we do in our Beer-Barbecued Chicken recipe and just pour beer into the cavity. If you don’t want to use beer, water or chicken broth will work too.
