Mysterious duck

[Chandler0206]

One of my new ducklings has had its identity mystify me and I was wondering if anyone could help. I know that one is a female crested mallard, but I have no idea what the black one is. Could someone help.

Is it truly black or a dark chocolate brown? I'd guess a khaki Campbell's.

Black and now its head has a green sheen to it

Black Runner or Cayuga?

If it stands and runs around like your other duckling, Cayuga... if it is more upright than the other, Runner...

Now he's black with a greenish tiny to him
