Place the hens on their backs for a final 10 minutes of cooking. The simmering broth will deglaze the pan as the birds roast, making a gravy. Remove from the oven and pour the cavity juices, including the rosemary and garlic, into the pan. Remove the rosemary and the trussing string, and let the hens rest in a warm place for 5 minutes before carving. Serve with the giblets and onions, if desired.
