I am just starting out smoking and I bought a Char-Broil propane smoker for a beginner unit. I have done a couple of whole chickens with pretty good success. One plain and one with a rub. During the two, I ran into a couple of issues that I have questions about. The first time, I used hickory chips that had been soaked for several hours. They stopped smoking and turned black in about an hour. The second time, I used some hickory chunks. They did the same thing but took a little longer. Is this what should happen to the flavor wood? The other question is about the water in the water pan. The instruction book said a whole chicken should take about 3 hours and use a gallon of water. Well...I probably added 4 or 5 gallons of water. Is this normal? Just trying to get started out on the right foot. Thanks.
