Wash chickens thoroughly inside and out under cold running water, drain well and pat dry with kitchen paper.
Chickens are best placed on a plastic board, which can be easily cleaned after use.
Place the chicken on its back and use a pair of poultry shears (see tip) to cut it open from the bottom to the neck, parallel to the sternum.
Turn the chicken over. Cut in half along the spine.
Place the chicken halves in a large freezer bag. Mix oil and paprika powder in a glass. Leave about 2 tablespoons of seasoning oil in the glass, divide the rest between the two freezer bags. Close the bag and massage the seasoning oil into the chickens with your hands.
Place in the refrigerator for about 1 hour.
Preheat oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer). Place the chicken halves on the baking tray with the cut edge facing down and sprinkle with sea salt. Add 2-3 tablespoons of water.
Bake in the oven for about 1 hour. As soon as the leg meat starts to come off the bone, the chicken is done.
After approx. 30 minutes frying time, brush the chicken with the remaining oil mix and fry for another approx. 30 minutes in the oven until crispy.
