Preheat broiler. Cut chicken into serving pieces. Line a broiler pan with foil. Place chicken on prepared pan. Combine butter, garlic, parsley, rosemary and thyme; mix well. Spread top of chicken pieces evenly with a small amount of butter herb mixture. Broil chicken, turning and coating frequently with remaining butter herb mixture, until juices run clear when thickest portion of meat is pierced with a knife, about 30 minutes.
