It depends on the size of the chicken. A chicken weighing about 3 kg should put about 6 kg of water. Let the ingredients fully release nutrition and fragrance with the slow increase of water temperature. If you use a rice cooker to cook chicken soup, you can put water that has just not been used. When you start to stew chicken soup, don't use boiling water, and don't keep adding water halfway. Chicken soup should be cooked in cold water, and the water should be added at a time, and it is forbidden to go halfway.
