Before explaining the process of pinioning ducks we want to first make the following comment. Many people think it is very cruel to pinion your exotic ducks. However there is a very good reason for pinioning. These ducks are exotic species and the last thing we want is for them to fly away and cross breed with indigenous species. If you argue that you are going to keep them in a fully enclosed aviary the question is still, how will you deal with excess breeding stock? The moment you want to sell to others, your ducks have to be pinioned because not everyone has the luxury of an enclosed aviary.
Once the sexing is done the ducklings can be pinioned. Males and Females are pinioned on different wing.
