Black and white manky mallards

Observation - Black and white manky mallards. Description: I think these are all black and while manky malards ie cross breeds with domestic ducks which are in themselves sub-breeds of mallards. They were mixed in with normal mallards and have the same body shape and bill shape. Most have the right colour legs

I think these are all black and while "manky" malards ie cross breeds with domestic ducks which are in themselves sub-breeds of mallards. They were mixed in with normal mallards and have the same body shape and bill shape. Most have the right colour legs and beak though a couple seem to have almost black beaks.

Saw one group of chicks which were mixed some normal mallard colours and others were very very dark but didn't manage to get a photo of those.
