I smoked two half chickens yesterday for a Super Bowl party today. What is best way to heat up and really crisp up skin?

What does WARP 10 mean?

Oil, to crisp my skin, once they're about 10 degrees shy of temp, I warp 10 my grill, lid open, and go about 2-3 min each side, flipping every minute. With the grill lid open, the skin will crisp without drying out the meat, like searing a steak. Sometimes I add a sauce, which will Carmalize nicely.

I would.

If you put them on the grill you could possibly dry out the meat the broiler will just crisp the skin . Just take the chickens out of the fridge about twenty minutes before you broil them and they should be warm enough to eat with crispy skin

Put them under the broiler for a few minutes
