How to make
Wash and dry the duck.
Smear it very well inside and out with the orange sliced in half.
Mix together the salt with the black pepper and paprika and smear the duck generously all over with it as well.
Place the duck in an oven dish, pour in the chicken broth, juice of 1/2 the orange. Arrange slices of butter on top of its breasts.
Cover the duck with aluminum foil and bake in a preheated 430°F (220 °C) oven for 20 min., then lower the oven to 320°F (160 °C) and bake about 3 1/2 - 4 hours, depending on its size.
30-40 min. before the end of baking, remove the foil to allow the meat to crisp and gain a golden, crunchy crust.
During baking, baste the duck periodically with the resulting sauce.
