Place chicken, onion, allspice seeds, bay leaf and cloves in a large pot and fill with water. Cook for at least an hour, turning the chicken occasionally. Cut carrots and celeriac into smaller cubes. Set the cooked chicken aside on a plate and remove the spices and onion from the broth. Add the noodles as well as the vegetables to the broth and cook for about 8 minutes. Meanwhile, take the chicken apart and scoop out the meat. Cut the meat into small pieces and add to the soup, bring to a boil briefly.
