I've used this REC: Chicken Stock recipe from Cook's Illustrated with great success...
It takes less time than usual and would, I'm sure, be just as good with little or no salt added. The hardest part is cutting up the chicken into such small pieces.
Chicken Stock
Recipe By :Cook's Illustrated
1 tablespoon vegetable oil
1 medium onion -- cut into medium dice
4 pounds chicken backs -- and wing tips, or whole legs cut into 2-inch pieces
2 quarts boiling water
2 teaspoons salt
2 bay leaves
Heat the oil in a large stockpot or soup kettle. Add the onion; saute until colored and softened slightly, 2 to 3 minutes. Transfer the onion to a large bowl.
Add half the chicken pieces to the pot, saute until no longer pink, 4 to 5 minutes. Transfer the cooked chicken to the bowl with the onion. Saute the remaining chicken pieces. Return the onion and chicken pieces to the pot. Reduce the heat to low, cover, and cook until the chicken releases its juices, about 20 minutes.
Increase the heat to high, add the boiling water, salt and bay leaves. Return to a simmer, then cover and barely simmer until the broth is rich and flavorful, about 20 minutes.
Strain the broth, discard the solids. Skim the fat.
The broth can be covered and refrigerated up to 2 days or frozen for several months.
