Add the finely chopped parsley and chives and season with sea salt and freshly ground black pepper.
Mix well with a wooden spoon until all the ingredients are incorporated, and get a soft butter paste.
Cut it and remove the chicken spinal cord together with the neck part with a knife or kitchen scissors.
Insert the handle of a wooden spoon under the chicken skin, and peel it from the meat in the area of the breast and thighs.
Season the chicken outside with sea salt and freshly ground pepper and massage it well into the skin.
Fill the whole amount of flavoured butter under the skin, massaging from the outside to reach all sides.
Grease the oven tray with olive oil and place the chicken in it. Cut in half the lemon you peeled and put it in the pan.
Cover with aluminum foil and place in the preheated oven at 180 C Fan (356 F) for half an hour.
Remove the foil, baste the chicken with the melted butter from the pan and put it back in the oven at 160 C Fan (320 F) for 45 minutes.

Notes
Check the roasted chicken; if it is not copper and crispy, you can put it under the grill for five minutes.Let the chicken rest for 10-15 minutes after cooking before carving. This allows the juices to redistribute, ensuring the meat stays moist and tender.
