Preheat Grill: Prepare for two-zone grilling using lump charcoal and targeting 450 degrees Fahrenheit in the grill.
Season Chicken: Coat chicken in olive oil and apply dry rub. The rub will stick to the oil. Be sure to apply rub under skin on breast, thigh and leg.
Grill Direct: Place chicken on direct heat skin side down for 4 minutes or until the skin has a good sear. Flip Chicken and sear over direct heat for an additional 4 minutes to get a nice char.
Grill Indirect: Move chicken to indirect heat and continue grilling covered until the internal temperature of the chicken reaches 155 degrees in the thickest part of the breast (about 15 minutes, depending on each piece, knowing smaller pieces will cook quicker, thicker pieces like the breast will take longer).
Glaze Chicken: When meat reaches 155 degrees Fahrenheit brush first coat of glaze over all sides of chicken with a silicone brush and continue grilling covered. When the chicken reaches 160 degrees F, remove from grill and apply the glaze a second time.
Remove and Serve: Let it rest for about 5 minutes, then serve.
