I have a few DP roos that I need to process, one is almost 3 years old, the rest are 8 months and less. The 3 year old and two of the 8month are very large and full breasted. I have a friend with a smoker and was wondering if the 3 year old would be good for smoking, or should I just use the younger birds. I would like to do 2 or 3 that way.
