What is this duck?

[MommaDuck]

I got this duck yesterday with three other ducks. The others are Blue Swedish but this one really doesn't look like the others. Much darker, and no yellow chest like the others. This one is also the calmest of the four and I posted some pics yesterday and this was the one on the door of the cage. Is it a Khaki Campbell? My five year old took the pics and the lighting isn't the best.

Yes I'd say Khaki Campbell

Here is my post from yesterday. This one is the one on the far right in the first pic and the one on the door. The chest does look lighter in those pics but it isn't.

Khaki Cambell, great layers, wonderful buggers.
