What breed is this
They look like Calls, post your pic here and see what the mallard folks say http://www.backyardchickens.com/t/754458/mallard-thread-not-rouens-mallards/1280#post_15880357
They are beautiful ducks maybe they are Mallards maybe Snowy? I have no idea but love their coloring.

Looks like 2 very pretty Muscovy's Make shift pond looks good, make shift house is worrisome with the predators we have here in the USA, ducks are every predators menu and need to be secured thoroughly at night especially.
