I'm going to be using my new Brinkman electric smoker for the first time. I will be smoking ribs and chicken leg quarters. The instructions give an estimate of 45min/lb for the ribs but nothing for the leg quarters. I know I'll be using their temp to determine when the legs will be done but I'd like to at least try to have the ribs and chicken done about the same time if possible. I've got 6.5lb of chicken and 9lb of ribs. At the estimated 45min/lb for the ribs they'll take about 6.75hrs. When should I put on the chicken?
