Please identify this breed of duck for me in VT

[BikerBabeRules]

Hi-
An old farmer gave me these ducks. The dark one is the male Rouen but i'm not sure what the females are. I'm getting one duck egg a day and the male is protecting his girls. I'm supposing these eggs are fertile even though she's off the nest the moment she lays them, I've seen her. I know they lay a clutch and then go back and set them. I'm collecting them every morning right after lay and incubating them for fun. I would like to know what breed the girls are, how long they will lay for and in Vermont, it's going to get below zero tonight so I can't leave them for her in the barn in the hay to come back and set on and hatch herself. It's to cold, right? Thanks for any information!

Maybe a magpie or swedish?

first ones Blue swedish and the other one looks like magpie, and the third one either a rouen or mallard.

the 2 blue/black and white ones are blue sweedish/rouen crosses . blue sweedish are usualy slimmer and theydont have the patch on the wing that looks like the mallard . I have roen /sweedish ducks and they are identical to yours

blue swedish. I think the first one, and the other one everyone thinks is a magpie is also a blue swedish.
The last one could very well be a rouen.
