There's a gland under their wing that secretes oil. they then stick their beaks under their wing and spread the oil on their feathers. Since oil naturally repels water, it just rolls off.

Because of a natural oil that is produced in the duck to coat the feathers, adding to buoyancy and keeping the duck insulated by not having the water soak into the feathers.

it rolls off the ducks feathers because there is a oil that keeps the water of them. the oil lets them swim and that how chickens can't swim because they don't have that oil that keeps the water off their bodies.
