Black. Note the characteristic 'stripe' of colour down the back at the root of the down. This is typical of appleyards. This baby is not yet dry so the colouring is easier to see than it will be later.

The two in front are black. The one on the left has a more pronounced colour on its bean (that teardrop-shaped bump on the end of the bill). A dark bean is preferred. The duckling in the back is a chocolate.
