BTW welcome
Pork is up and Bacon, the best part of the pig, is up about 25%.
Beef is up because of the drought in Texas.
Chicken is up too.
BTW smoking 6 chickens take 6 to 8 hours.
You cook them to @ 145 degrees and let rest for 15 minutes. The will rise to that magic 165 while resting..........
The slow smoking will insure a juicy bird that can be reheated and stay moist.
You suggestion at 250 works for 1 bird. But you can easily over cook it.
I recommend the use of a remote digital thermometer when doing the bird.
Also do the in the beer can style in a shallow pan. This makes it unnecessary to turn the bird.
For flavor I toss apples and oranges on the wood to produces a wet smoke.........thus no need to baste unless you want to with sauce at 120F
