The next production phase, which the French call gavage or finition d'engraissement, or "completion of fattening", involves forced daily ingestion of controlled amounts of feed for 12 to 15 days with ducks and for 15 to 18 days with geese. During this phase, ducks are usually fed twice daily while geese are fed up to three times daily. To facilitate handling of ducks during gavage, these birds are typically housed throughout this phase in individual cages or small group pens.
