For the seasoning: Combine the cayenne, paprika, salt and pepper in a bowl, mixing well.
For the chicken: Preheat the oven to 300 degrees F. In a bowl, mix the greens, onions, peaches, 1/4 cup butter and 1 tablespoon of the prepared seasoning, mixing well. Next, open the center cavity of the chicken and stuff it with seasoned greens/fruit mixture. Then drizzle the remaining 1/4 cup butter over the skin of the chicken. Dust with the remaining seasoning.
Roast the chicken for 50 minutes, and then remove from the oven. Raise the oven temperature to 450 degrees F, allow to heat for 10 minutes, and then place the bird back in the oven and finish until skin is crisp, 8 to 10 minutes. Remove the chicken from the oven and allow to rest for 5 minutes before cutting or carving.
