never had a whole lot of success with smoking chickens. tried numerouse times. brine, no brine, diiferent woods. came to the conclusion the beer can chicken is the easier way to go with better results. you might try putting a wood chip inside the chicken if you go the beer can route. that will give it a little bit of that wood flavor.
but by and large, when it comes to smoking birds, turkey & pheasant work best.
HOWEVER, i smoke my jamiacan jerk chicken, but it's a whole cut up chicken, not a whole chicken.
