I got a duckling with another one from a feed store and the lady didn't know anything about them she didn't even know their age well the other is I believe a khaki campbell and im not sure about this guy or girl then I have another duck that I got that I'm not sure what she is, she is smaller then my other ducks, she is like half there size.

The one in the first and the second picture looks like maybe a blue or gray runner.
The other o e I don’t know.

I would say the one in the first and second picture is a Blue Runner, and the last one might be a cross of sorts.
