Also, if you get a high or low reading, re-take the temperature! It may be correct, but it is best to confirm the temperature if it is unusual, and the doctor will ask you if you did take it again, as sometimes there are errors with thermometers, or technique in taking the temperature.
Grilling Guidelines. Only CorningWare made from the original formula can be used on grills. The same guidelines should be used as for stovetop cooking. The grill on which the dishes are placed should be only moderately hot, with no direct flames touching the bottom of the dish.
If you had stored it in a corningware bowl or similar bowl and the Fat/oil from the chicken(like juices from a rotiss chicken) collected at the bottom, I would also have said 3 days. But Cooked Chicken from the grill will last 7 days wrapped as you have it. I assume its not loaded with BBQ sauce.
