This is how I learned to cook chicken 40 years ago.
Always got the butcher to split into halfs.
Fired up the barrel grill with fire under about half .
Chicken halfs were cooked about 1/2 indirect & 1/2 half direct.
The fire is far enough below the chicken allow about 20 min between turning without burning.
Just before the chicken is done slather with BBQ sauce & let sear ( ok I learned to like a the taste of burned BBQ sauce)
My CB-740 is just a manufactured small version of the homemade barrel cookers I first cooked on.
The cooking chamber is deep , the coals can go 12 in below the grate.
