Set coals inside grill and light, set grate on top and close the lid to wait for the coals to cool down enough to where they turn from black to white. This will take about 25 minutes.
While you're waiting you'll want to season your bird. Unwrap the bird, remove bag from inside if there is one and discard. Dry skin with paper towels. Rub a bit of olive oil on skin and coat with your seasonings of choice. (we have a link above for our dry rub)
If you're using a chicken throne fill it 3/4 of the way full, there should be a line. If using just the can dump or drink 1/4 of the contents.
When coals are white set cast iron skillet in middle of grate.
Set can or throne in middle of cast iron skillet and set chicken on top sliding the open cavity over the opening so it sits flat and isn't falling over.
Close lid on grill and cook until middle of thigh reaches 165 degrees F. This will take 1-1.5 hours depending on the size of the bird.
Remove with pot holders, set on cutting board to rest for 10 minutes before slicing.
