Gender and breed?

[BradenLeeP]

So I’m new to raising my own ducks. I grew up working at a local dairy that had ducks and a few thousand chickens but...
I was hoping someone with more experience would know what gender and breed my two big duckies are. They’re roughly 7 - 8 weeks old and I got them at a day old. I believe the brown one is a Rouen female and the grey one is a Blue Swedish male? I’m just guessing by the size of them... I will post pictures for a discussion starter. Thank you!

Blue Swedish and what looks to be a Mallard.

Females Quack, Males sound like smokers.

Is there a reference to the sounds you speak of? I don’t know a lot of smokers

Smokers normally have rougher voices, you could google male vs. female duck quacks and listen to them then compare them to your ducks.

Thanks Isaac! I've actually used this quite a bit with all of them, I've got 5 now! I appreciate the reference.

blue swedish and mallard. i wouldn’t say the mallard is a female just based on its size, they are generally smaller than swedish
