Preheat your oven to 350 degrees. Remove chicken from wrapping, rinse the chicken in the sink, if there is a "goodie bag" inside the cavity, remove it. We all have accidentally baked the livers and gizzards in the chicken exactly once. I normally discard the livers and gizzards, but you may want to fry them up. Prepare a compound butter by placing the butter and seasonings into a small bowl, mix well.
Cut lemon in half, and squeeze 1/2 of the lemon's juice into the compound butter. If you really like lemon, add a little lemon zest to the compound butter. Chop herbs of your choice and add those to the butter. I have made this with chives, rosemary, and thyme, and combinations of those three. If you are going to use rosemary, use only about a tablespoon or the rosemary will dominate the chicken. Now, carefully place the compound butter between the skin and the chicken.
You can separate the skin from the chicken easily by simply reaching in and spreading your fingers. Spread the compound butter starting at the breasts, and then over the drumsticks. You are likely to have some butter left over, spread remaining butter inside of the chicken cavity, and onto the outside skin. Place the chicken breast side up into a baking dish. Put lemon halves inside the body of the chicken, and if you have any herbs left over you can add those inside of the chicken cavity as well.
By now the oven is fully heated, and you can place the chicken into the oven. Bake for about 50 minutes. Check chicken for doneness with either a meat thermometer by placing into the thigh, chicken is done at 180. Or, if you do not have a thermometer, cut the chicken slightly at the thigh and see that the juices run clear. Remove chicken from oven, and let it rest for about 10-15 minutes. Letting the chicken rest is actually crucial to a moist chicken, if you let the chicken rest, you will have a moist chicken because all of the juices flow back through the meat.
