I picked these two up at TSC. I saw them and just couldn't resist but I have no clue as to what they are. The first one is yellow with grey spots on its beak, feet and head, with an all grey back. The second is moslty black with a little yellow on the belly and a black beak and feet.
They are both crested ducks, one looks like a crested swedish. Privett hatchery had those at one time. Not so sure on the other one but it looks like a spotted, harlequin pattern duckling but I know that the Ancona (spotted) isn't the only duck with that pattern, Calls come in that too.
