Place the chicken on the side of the grill where there is no direct heat, using the beer can and the legs as support. Cover the grill and allow the chicken to cook undisturbed for an hour. After this time, check the chicken, and if you’re using a charcoal grill, top up the coals as needed.
Continue checking every 15 minutes until a meat thermometer reads 165°F in the thickest part of the thigh. Depending on the grill temperature and chicken size, cooking should take approximately 1.5 hours for a 4-pound chicken.
Alternatively, you can also check for doneness by slicing into the thigh. If the juices run clear and are not pink, the chicken is ready.
