Make dry rub mix by combining all spices in small bowl. Stir or whisk well, to fully blend ingredients. Set aside.
Rinse and pat dry (with a paper towel) one or more whole chickens. Remove any giblets that may be inside the chicken cavity, and discard. Cover the entire chicken generously with dry rub mixture, patting it into chicken to adhere. Sprinkle some dry rub mix into the cavity of the chicken, also. Tuck the tips of the chicken wings under the chicken, to hold in place. Tie the front legs of chicken together with cooking twine. It's a good idea to do this, because it helps the chicken cook more evenly.
Start the Traeger grill on SMOKE setting, with the lid OPEN, until fire has ignited and is smoking (about 4-5 minutes). Set temperature gauge to 375°. CLOSE LID. Let grill preheat for 10-15 minutes. Add a small aluminum pan of apple juice (or cider) to the top rack of grill (this helps keep flavorful steam circulating while roasting). After grill has preheated, place chicken directly on the grill grate. Cook at 375°F (with lid closed) for about 60 minutes, or until internal temperature reaches 165°F.
To test for internal temperature, insert the temperature probe into the chicken in between the leg and the thigh joint. You will need to also check the internal temperature of a chicken breast, to ensure it also has reached 165° temp. NOTE: If it looks like chicken is starting to blacken on top near the end of roasting time, lightly cover chicken with aluminum foil; continue cooking until done.
Once chicken has reached an internal temp of 165°, remove from grill and place on cutting board or tray with rimmed edges (to catch any juices). Untie chicken legs by slicing through and removing cooking twine. Let chicken rest for 15 minutes (to let juices inside redistribute throughout meat). Slice and serve!
NOTE: Caloric calculation is an estimate for a WHOLE 3 pound chicken. Calorie counts will vary, due to pieces of chicken eaten, OR the total starting weight of the chicken.
