You might consider buying a AMNS. It will solve the chip problem, & you can leave the smoker unattended for hours. No chips to add. A lot of the MES guys here use one. It makes it TOO easy, and you get consistent TBS, throughout the smoke. I have an MES & an AMNS, and would not go back to using the chip tray. A lot of guys here feel the same. Your bird looks great so what your doing is working well for you. This just an option that is available that you may want to try. Good luck & happy smoking!
