Your mix of wood should be fine. I think the better question is what temp should I be cooking at? Chicken will not be very good cooking below 325. Skin turns to rubber, instead of being crispy.
i'd try to keep the temps around 300 then bump up at the end fo finish. Remember chicken is small meat parts, it should never need more than 2 hours in the heat. Ribs, 3.5 hours at 300, depending on weight.
If you need more than 2 hours to finish your chicken, there is something terribly wrong.
