What breed of duckling do I have?

[jehaz]

I bought some ducks from Tractor Supply but I am not 100% sure what kind they are.
I think they are Khaki Campbell. But they could be Cayugas or runners or something else.
The store said they didnt know but that they only buy from breeders so they are purebread.

Any ideas?

thanks, James

Khaki. Cayuga would be much darker. And runners would have white markings and more straight Almost penguin like structure.

I'm going to say khaki as well. Cayugas are black. Runners come in all colors and if this little one stands really tall and straight up then I would say it's a java runner.
