re: Chicken in a Can/Bucket

I don't understand where I went wrong. I remember in the earlier thread the guy said the woman who explained it to him said it had to exactly 15 coals. And probably 1/2 of those were still there when I took the bird out. I mean this thing was nearly as raw 3 hours later than it was when i bought it. I'll probably try it again but, I'd like to have some idea of what to do differently.
