Sure! At 225-240*F the Ribs will take about 6 hours, the Thighs maybe 2-3 tops, going to an IT of 175*F. Start your ribs, go the first leg of 3-2-1. When it's time, Foil the Ribs, go back in the smoker and add the Chicken. Finish the cook. They should come off about the same time or the thighs a little early. This is no big deal as you will want to Re-heat the thighs on the Grill to crisp the skin anyway. While the ribs rest , Grill the thighs and serve all together. Another option is to Smoke your ribs at the low temp till done then wrap them in Foil and Towels in a cooler to rest. You Crank the Smoker to 300-325*F and smoke the Chicken. The Thighs will be done in 45-60 minutes and have a great crisp skin. Don't sweat Bird on top or Ribs on top, chicken juice can't get through Foil and all will be cooked when they come off...JJ
