Call ducks?

[Kim925]

We just got these call ducks from a breeder. I've never had calls but I was thinking they would be smaller. Is there any way to tell if these are true calls? They just look exactly like our other ducks and I'm getting nervous. They do have dew claws that my pekins and rouens do not have. I was told they're a little over a week old.

No, I am afraid they are not Calls.
