I usually just add water, salt and pepper, sometimes onion. I don't taste a difference in the result with water or chicken broth, when doing a whole chicken. I made a chicken noodle soup on Sunday, I did use chicken broth in that. However, I just had two whole boneless skinless chicken breasts, so not much fat at all, with no skin or dark meat, cooked them on high in the broth for a couple hours, then shredded them and put in a large diced onion, celery, carrots, and then egg noodles and corn at the end. Made a very satisfying soup.
