Combine all the ingredients in a very large stock pot. Bring to boiling; reduce heat. Cover and simmer for 2 hours. Remove chicken pieces.
Pour broth through a large sieve or colander lined with 2 layers of cheesecloth. Discard vegetables and seasonings. If using the broth while hot, skim fat. (Or chill the broth and lift off fat.)
If desired, when bones are cool enough to handle, remove meat from bones and reserve meat for another use. Discard bones. Store broth and reserved meat, if any, in separate covered containers, and refrigerate.
This recipe yields about 10 cups broth and 5 cups meat.
Comments: One of the advantages of cutting up a whole chicken yourself is putting the leftover bony pieces to use in homemade chicken broth. Or purchase backs, necks, and wings from your supermarket.
