I purchased these 2 ducklings at a store that is supposed to only carry blue Swedish, Rouen, mallard, Pekin, and khaki Campbell. The store told me they had only Pekin ducklings and whatever I got, but they don't know the ones I got. They are not any of the breeds the store sells, they look like Pekin ducklings except they all have a small black dot on their head. Could anyone help me identify their breed? I have attached some images below.
