Help me sex my new ducklings and confirm what breed my ducklings are

[Hamudazahabi]

first video = female
second video = hard to tell maybe wait a bit longer
third video = hard to tell but i think i heard potential quacking, and seems to be getting mallard like feathers on its back
fourth video = hard to tell but in the sound only video potential quacking
fifth video = i would guess male as still peeping

Thanks for helping.

egg duck could mean duck eggs so any random mix of duck breeds
also the person you bought the ducklings from might be lying or the person who sold the eggs might be lying

I don't think so because they also have ducks they call "meat ducks" and they usually refer to pekins. Also, I translated the name to you from Malay, as they originally call it "itik telur" for the egg one and "itik daging" for the meat one, as in Malay "itik" means "duck". When I search "itik telur" online, I see pictures of Khaki Campbell ducks but I notice that most of the shops selling baby ducklings put pictures of mixes of small ducklings that looks just like mine.

when i am buying ducklings i like to meet the parents so if the person selling the ducklings are not the parents owners then i probably would go for someone else but that is just me, and you already have them (not trying to be rude or anything just something thought might be handy for new duck parents)

Yeah I get what you mean, but this shop basically hatches a lot of eggs right when they are layed far away at his farm, then ships so many ducklings to the shop and sells it, so it's not a person who sells it here doesn't know the parent either. It's the only source here as these shops are the only ones near.

Their is lots of good pictures and information of Swedish ducks here
They do seem to have blue green feathers. Hope it helps

Thank you very much. Yes, you're right, I noticed blue on the wings of many of these Swedish ducks in the photos their.
Thank you very much.
