Rinse chicken in cold water and pat dry. Put celery on the bottom of the crockpot. Put 1 sprig of each herb into the cavity of the chicken. Place chicken on top of the celery. Cut up the rest of the herbs and sprinkle on top of the chicken. Add ground pepper to taste. Peel garlic, leave skin on, and place on top and around chicken. Cook on low for 8-9 hours. The cooked garlic can be used in place as garlic butter for the French bread. Just squeeze and spread onto bread slices.
