You probably mean down, but down is not a feather, it is down.
A male duck is called a drake. A female duck is not called a drake (duck or hen)Drakes (male ducks) of most breeds have a 'drake feather' on top of their tale, a feather that looks like it has been curled with curling tongs... The markings of drakes are different than those of the ducks in most breeds.
Check out that plumage. Once your tiny ducklings grow to 2 months old, there will be one surefire way to tell the males from the females. Look at your duck's tail. At the very end, there will be one obvious feather, which usually curls down in a very distinctive curl. This is called the sex feather. This feather is located on all male ducks. The feather is present even after a molt, so the season will not deter you from being able to sex your ducks.
Duck down and feathers are used in pillows.

When a feather is in the water, it gets wet and absorbs some water. When a feather is still on a duck, the oil secreted by the ducks skin is in the feather and prevents the ducks feathers from getting waterlogged. Otherwise the feathers on the duck would get heavy with water and make it impossible for the duck to stay on top.
When ducks are adults, you can look for the easy to tell "sex" feather on a male. This is a feather at the top of the base of the tail that has a curl in it. It curls down towards the birds back. If the bird is a male it will have this sex feather.
