Preheat oven to 425 degrees.
To prepare the chicken, place the chicken breast side down. Using kitchen shears cut along the backbone to remove on both sides to remove it.
Turn the chicken over, with the breast side facing up and press firmly on the breast bone to flatten chicken.
Pat the chicken with a paper towel to remove moisture.
Mix finely 2 oz of softened butter with finely chopped parsley, thyme, chives, garlic and ½ tsp salt.
Use your hand to loosen skin from the breast to create a pocket. Place herb butter under the skin and spread to cover the meat. Place chicken on a baking pan.
Spread additional 1 oz of butter on the skin of chicken then sprinkle with remaining salt, black pepper and five spice powder then place into preheated oven.
Roast for 45-50 minutes or until the juices run clear (internal temperature of 165 degrees).
