What breed are my ducklings?

[JuliePoole]

I have four ducklings and two of them I thought were pekins but now I wonder if they aren't buff. It looks like some light brown feathers might be sprouting. Help!

They look like my pekin ducklings...

They are Runners

Agree with Gray Farms. They are very cute.

So cute!
They look like runners to me, but I don't have much experience with them
