- Heat oven 375 F. 
- Place oranges in cavity. 
- Combine grated orange peel with chopped sage leaves, butter (kind of softened), salt and pepper. Rub mixture under chicken skin all over; reserved some for the outer skin. 
- Place chicken into roasting pan, tie legs with twine. Rub remaining butter mixture  all over outer skin. 
- Roast chicken for 2 hours; 15 minutes before 2 hours, take out chicken, brush with marmalade all over. 
- If you have rack set for the roasting pan, it would be a great use instead placing the chicken right into the roasting pan because once chicken is done, it would most likely stick to the pan. 
- Occasionally, brush chicken with melted fat inside the pan for greater flavor.
