Are you working with a calibrated therm? Seems too soon to be thoriughly/safely cooked. Also make sure as to where you place the meat probe, it should be in the thigh area and not touching any bone. Good luck my friend.
Like they ^^^^^ both said. You have to make sure your thermo-meter is reading correctly. Then make sure your not touching the bone, I check it in the breast but not more than a couple of inches (2") in. Like they said again check it in a couple of places.
I have grill/smoked last 20 or so thanksgiving turkey et. at 350 degrees and the time per pound is 14.5 minutes to be 170 degrees internal on average.This has not let me down, but as mentioned cook to the internal.
