Remove skin and excess fat from chicken. Cut up chicken and place in a pot and cover with water. Bring to a boil, then lower heat and simmer until meat falls off the bones. Drain the broth. After the chicken has cooled, pick the meat from the bones, shredding into small pieces.
In a large skillet, cook the beef and pork together, stirring often and breaking into small pieces, until the meat is just gray. Drain fat. Put meat and chicken into a crockpot or large pot. Add the rest of the ingredients. Cook over low heat for 3 hours, stirring from the
bottom of the pot often, or if using a crockpot cook for 5-6 hours at a low setting.
