I also almost always rotisserie a whole chicken.
The process has changed over the years, my latest variation with the outdoor rotisserie covered BBQ:
1) Fire up the BBQ, over down, with all three burners on full. This generally raises the temp to about 500 degrees.
2) Meanwhile, rinse and pat dry a whole chicken. Mount it on the rotisserie spit, trying to keep it balanced and so it will be positioned later at the center of the side/back infrared ceramic burner on the BBQ.
3) Tie the legs together with stainless wire. Tie the wings against the body with a big loop of wire.
4) Brush olive oil all over the bird. Then rub in some salt-free herbal seasoning (I use the organic stuff from Costco). Also put a teaspoon of the dried herb mix inside the bird.
5) Place a stainless warming tray on top of the burners (I remove the BBQ grill for this) and allow the temp to get back to up to 500. Place spitted bird in BBQ and turn on rotisserie motor. Keep burners on full and close cover. DO NOT LEAVE THE BBQ. The object here is to subject the bird to high heat for a short period in order to sear it. Without the drip pan, oil and bird fat will ignite on the burners and incinerate the bird. Not good if you don't like eating charcoal.
6) When dripping fat from the bird starts to smoke in the drip pan, turn off the center burner but leave the two outer ones on. Leave the bird in this state until the skin has yellowed, indicating searing. This generally takes about five minutes.
7) Turn off all burners and light the back side rotisserie burner, on full.
8) Oven temp will gradually drop to between 150 and 200F. Don't worry, the bird temp is higher from the rotisserie burner.
9) I've found that using this technique, a five pound chicken might take between 1 hour and 1.5 hrs to cook to suitable internal temp. Smaller birds cook faster than larger birds, so one needs to monitor the process. I generally cook to an internal breast temp of 165 to 170.
10) The final result is tender and juicy, with some delicious drippings in the drip tray for flavoring the cooked chicken or side dishes later.
My only reservation about brine treatment is that salt tends to draw juices out of meat rather than keep them in. I suppose with searing, however, the juices can be sealed into the meat so it isn't lost in cooking, even if brine has been used.
I do brine cabbage when I make Kimchee... LOL...
