Twice I have tried smoked turkeys on the egg and both times the smoke flavor was very little to non existent. Bird flavor and moistness was great but the smoke just wasnt there. Used Cherry chunks and was told not to overdo it on poultry. I used two chunks about fist size both times. Do I need to add more? I arranged them so that the fire would hit them later, which it did. Had a nice smoke coming out of there for a while. What am I doing wrong? Birds were cooked at 325.
