What breed are these ducks?

It looks like you have runner ducks to me here's mine when they were 3 weeks old, with some week old mallards...

This is a great help. Thank you. As the black one does look exactly like this when standing. Thanks

You can tell a duck and goose easily apart by the shape of their bill though. Ducks have long, flat bills. Geese have more wedge-shaped beaks.

I don't know what that big duck is but the dark one is probably runner.

No problem Runners are a kick to watch; the way they stand up is pretty unmistakeable .... They're very skittish, so let your friend know they're not really "cuddly" ducks...they rather you look than touch them haha

Edit on the goose question...the buff one could be an African goose, but sometimes runners can be different sizes too...male might be a tad bigger...or the runt of the litter might be extra small....the bills both look like runner bills though.
