Ideally, I would use a Weber Kettle with a Medium Sized Vortex setup. I was skeptical of the Vortex, but became a believer after my first evening of playing around with it. The added convection airflow really does make grilling crispy chicken an easy task. You want the dome temperature in the grill to be around 500 degrees F. After that, you can place the seasoned chicken on the grill and rotate it every 20 minutes until the chicken is very crispy and has an internal temperature over 165 degrees F.
If do not have a weber kettle with the vortex accessory, then setup whatever grill you have for indirect cooking at a temperature over 450 degrees F. If you have a weber kettle with out the vortex, then setup your baskets on the outside and get the grill not and hot!
