Their names are Riri, Fifi and Loulou. Contrary to what one might imagine, they are not ducks but roosters. They are among the stars of the Potager des Princes de Chantilly. Every day the trio sprints on the gallinodrome, the racetrack of these gallinaceans, under the encouragement of visitors who each have their favorite. On this Saturday followingnoon, it is Riri who arrives first at the manger following a race on all legs.
