Wash chicken and remove giblets from inside. Dry chicken and rub with butter on all sides. Sprinkle with salt and pepper. Be sure to get some salt and pepper on inside.
Put in crock pot in early morning (about 8:00 a.m.). Turn crock pot to low - let cook all day. When returning home from work about 4:00 or 5:00 you will have a delicious baked chicken. Remove from crock pot with spatula to keep from falling apart. You will have about 2 cups of chicken broth in pot. Use for gravy over rice or mix with Stove Top stuffing instead of water.
