foto Elise Biersma foto Elise Biersma In the beginning of July, non-breeding geese started moult. We catch this group of flightless birds by pushing them from a distance towards the net. The geese are kept in this pen to empty their intestines. After two hours, the geese are put into boxes to be processed.
