Are these mallards?

I bought these ducklings months ago. I was told they were bantam call ducks. Based on the way they fly I doubt it. Is it safe to also assume these are a Trio? I have the two brown and one white.

Pictures arent working, lets try this..... Also the pictures do not do the colors of these guys any justice.
