It's SO easy. Try it this weekend. You don't even have to stir. You will need some chicken. This can be a whole broiler, chicken pieces, chicken wings, frozen pieces you find in your freezer that you're pretty sure are chicken, even chicken bones.
Bones are desirable.
Save expensive boneless chicken breasts for other recipes. The only part of the chicken that you don't want to use is the liver, which makes broth cloudy. Wash the chicken and put it in a large pot. You don't have to cut up anything. Cover it with cold water plus about an inch more.
