putting geese in boxes |
 |
 |
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. |

The long black feathers from the wing have fallen off the bird. During moult the geese grow new flight feathers simultaneously. Here you can see the short wings, which are still unable to carry the bird in flight. |
