If you people keep this up I'm gonna end up doing some birds tomorrow. I always brine my chicken and turkey. I've never brined it for beer can chicken (I'm sure it wouldn't need it). I just use 1 cup of kosher salt per one gallon water and chuck in whatever else I'd like the bird to taste like and soak it for 24hrs. If your not doing beer can chicken then it would definately do better brined just like turkey.
I found this site when brining some birds for deep frying http://www.ochef.com/152a.htm
We have had good luck following the guides here, but some sites say you can brine chickens over night just like turkeys?
Sure you can, with the same caveats-- buy a chicken that has not been "enhanced with a solution of...", or other words to that effect. Look for labeling that says "all natural" or similar.
If you get an Amish chicken it won't be treated.
I would also feel more comfortable using the brining table Chris supplied than the one showing brining for 12 hours. If the brine included tenderquick and salt that may be too much for chicken giving you a real salty bird.
