The guys covered the chips, B Daddy, but I, too, am curious about the brine time. Do you have experience brining a chicken that long? Do you use a very weak (salt content) brine? Where did you hear about brining a chicken that long?
You may have a solid method, and I'd like to hear about your technique. But, if you using any of the "standard" poultry brines, 13 hours is 3x too long. I brine whole chickens 3-4 hours, at the most. A turkey will go 13 hours, but not a 5 lb chicken.
