Even if it looks like it is cooked on the outside, it doesn’t necessarily mean that it is fully cooked on the inside. You should always check for doneness by placing a meat thermometer in the thickest part of the chicken drumsticks and check that it registers a temperature of 165°F - 175 °F. You can also cut into the chicken and check what the meat juices look like. If there’s no pink or red hue in the meat juices, your chicken is likely done.
