I would recommend throwing away the water in which the chicken was boiled at the beginning, put another clean water and let it boil again. Add whole vegetables (onions, carrots, peppers) cleaned and washed - do not cut them into small pieces because we use them only for soup, to make the base fragrant and tasty. Put 2 bay leaves, froth if necessary and when it starts to boil well, make a low heat and leave for 40-50 minutes.
