There are a few different ways to tell if a chicken is done cooking.  One is to use a meat thermometer. The ideal temperature for cooked chicken is 165 degrees Fahrenheit, so insert the thermometer into the thickest part of the meat to check. You want to pull the chicken from the heat when it reaches 160° F because the internal temperature will continue to rise as the chicken rests.  Another way to tell if the chicken is cooked is to cut into the meat. If the juices are clear, it's done. If they're still pink or red, it needs to cook longer.  Finally, a cooked chicken will be firm to the touch.
