Remove giblets from hens and discard; rinse hens with cold water. Split hens lengthwise, using poultry shears. Place in a 13x9x2 inch glass baking dish. Combine remaining ingredients in a small sauce pan. Bring to a boil, reduce heat, simmer 10 minutes. Pour over hens. Cover and chill about 8 hours. Remove hens from orange juice marinade, reserving marinade. Grill over medium coals or broil 15 minutes on each side or until done, basting frequently with reserved marinade. 4 servings
