Shown left is our main breeding drake, here in summer plumage. Below with two of his male progeny.

Although drakes usually retain a reasonably rich colouring ducks quite often become increasingly prone to white patches. This doesn't mean that the strain is impure in any way; often ducks with this tendency seem to produce a strong green irridescence in their offspring. Segregating sexes can help lessen the white feathers, as often they are hastened by rough attentions of the drakes.
