The temperature of the grill on medium to medium high heat will vary between 350-375 degrees. To ensure that the chicken is fully cooked all the way before removing off the heat, use a meat thermometer to check the internal temperature of the chicken. As long as the internal temperature of the chicken is 165 degrees, the chicken should be fully cooked and ready to eat. This is the safest way to ensure that the chicken is cooked all the way through. Thanks!
