Homemade chicken broth is so much healthier (and cheaper!) than stor bought broth. There are several recipes that you can use to make chicken broth at home, and really it is quite flexible - you can use whatever you have around the kitchen to make your broth. What I usually do is:
1) Bake a whole chicken. I put in a glass pan and bake at 400 degrees for 50-60 minutes. Shred the chicken - set aside the meat for another meal. (I typically use this meat to make Chicken Salad). Save all of the bones, skin, meat you can't get off the bone, and organs.
2) While the chicken is baking, chop and onion or two, several (3-5) cloves of garlic, 2-3 cups of carrots, and 8-10 stalks of celery. Place in a large pot with about a gallon of water and bring to a boil. Add salt, pepper, and spices to your liking. Add about 1/4 cup apple cider vinegar.
3) When the chicken is done being shredded, add all of the non-used parts to your broth mixture. Simmer on low for 12-24 hours (this will decrease your liquid by about half).
4) Strain your broth and package as you like - freezer bags, freezer containers, or jars.
