Duckling Breeds?

[Panda Ducktress]

I got these 5 ducklings from tractor supply. I love them to death, but am wondering what breed they might be and if there's a way to sex them without vent sexing as I do not want to harm them. They are still small only about a week old. I believe the two yellow and black may be Black Swedish ducklings. I am new to being a duck mom, and am enjoying every minute of it. If you just have random advice as well that is appreciated. I have been reading a lot. I know that I may need to get more females as I have read many stories that tractor supply has more males than females. I am prepared for that, but I would like to know their breed perhaps if anything.

Two of them I thought so, but the ones that are more black/grey are the ones that I am really unsure of. It may just be a sit and wait game.

Black and yellows are Black Swedish, yes. I’d say the solid blacks are Cayugas given their low-to-the-ground stance. If they start to walk with a tall-stance, they’re Black Runners.

The best way to sex them then is to voice-sex. Females get a significant voice change at around 3 - 4 weeks. Males later at 8 - 10 weeks. Alternatively, you can upload a video of their voices later, and we can voice-sex them for you
