Black vs Blue Swedish duckling identification

[StormsnSaugeye]

So I was excited to see when I got home that a mystery egg I literally found half in the water of like, the only river in this state, hatched this afternoon. This after he spent 48 hours just chilling and being smug inside his egg and finally getting me worried last night.
Anyways, Best ya girl here can tell, it's a Swedish duckling. However with the down being so dark I would think Black Swedish. However, he's got a fair bit of yellow on his bill. But his lil cheesy flappers (Feet) are pretty much pure black.
How long after hatching does the distinction between blue and black Swedish become apparent?

Could we have pictures, please?

Little guy is fresh out of the egg. And he (or she) sure was dramatic about it all.

You sure it's not a Mallard? If it is a Swedish, I think it's a Black

Pretty sure. It doesn't have the distinctive black stripe with two yellow stripes and most of its body has the dark down. If it is a black Swedish that makes me happy since they're a bit on the rare side. Before this I've mostly done rescues of geese, abandoned ducks of the pekin and khaki Campbell persuasion and two call ducks who eventually made an escape and settled on the lake I used to live by.
Blue Swedish ducks are nice but I am rather stoked for the black Swedish since for some reason they just strike me as 100% more adorable as young and adults.

Am I understanding correctly that you found the egg in a river? Are there wild ducks in the area? It doesn't look like a mallard as someone mentioned, but what about another wild duck subspecies?

Yeah it was just chilling half underwater when I found it. The only wild ducks Around here are mallards, shovelers, teals, Ruddy duck, cinnamon teal, and the occasional merganser. However, There are a large number of abandoned ducks around here as well (Which infuriates me). And based upon the coloration I am inclined to believe it's a blue or black swedish duck based upon the down pattern. Since it doesn't have any of the telltale looks of any of the listed ducks, I know it's not one of them. Plus there was no nest nearby. Suggesting it was lain by a duck that was indifferent to it/not feeling broody.
So I figure it's a Swedish, probably offspring of one of the abandoned ducks you can occasionally see. But I'm leaning towards black swedish.
If this were a wild breed I'd already be in contact with a wildlife rehabilitation center.

You can tell black from blue at hatch and yes, yours is black. Here is a picture of a blue Swedish mix duckling I hatched two weeks ago. Mine is much lighter.

Great point. Here the lil guy is dried off and you can definitely tell the color difference.
Cool. I've wanted to try a swedish duck. Glad it's the black one.
