Place the carrots in the bottom of a 4 1/2 quart or larger crock pot. Add celery, onions, and potatoes to the bottom of the pot. Add the water and sprinkle the vegetables with 1 teaspoon of the seasoning salt. Remove the neck and giblets from the cavity of the chicken and rinse inside and out with cold water. At this point, I removed the skin from the back of the chicken to reduce the fat content. Place the chicken, breast side up, in the pot on top of the vegetables. Sprinkle the remaining teaspoon of season salt over the chicken and add other spices, if desired. I would add some garlic and parsley - anything your family likes on chicken. Cook on the low setting for 7 to 8 hours.
