Put the whole chicken in the pot and simmer. SAVE THE STOCK! Take the chicken out, and let the pot cool on the stove. When it is at room temp, put it in the fridge for an hour or so, and the grease on the top will get hard. You can take it out with your hands, and throw it in the trash. Other than intentionally making stock, chicken soup, or need chicken for chicken salad, I am not sure why you would want to boil chicken.
