Are there any super common breeds of duck that you can tell their gender by sight right away? (Like within four days of them being hatched)

I think the white one is full Saxony. Time will tell.

i am still trying to learn how to vent sex. As my black East Indie don’t have the nifty trick of the bill.
But like i said not all lines are strong with that sexing by Bill color. I did have one duckling that was a 50/50 bill color and couldn’t guess the sex until he was older.

I learned from a Metzer video on YouTube, first hand watching on a farm, and using my day old ducklings (after video and first hand watching).

I did 3 ducklings last hatch... 2/3 are quacking. I'm hoping the other one starts quacking soon since it's my husband's duckling he picked.

I don't mind waiting until 5 weeks. I am sleeping with my peeepers tonight.

Sadly doesn’t work with mixes to my knowledge. If they are pure welsh the girls would have had a dark bean and light colored bill at hatch, and males have an all dark Bill and bean.

@Pyxis might correct me if I am wrong on sexing mixes of this breed, but I am pretty sure on it.

Yep, doesn't work on mixes. Doesn't work as well in well-bred lines, either. Holderread found that in WH that most closely matched the breed standard, it worked 70% of the time, compared to 90% in hatchery lines.

The title says it all. By super common I mean like kinds you can find at tractor supply. I want to make sure I get three ducks and no drakes. It’s almost $100 to ship three ducks to where I live and I’m just not sure that’s in my budget. If there aren’t, I will wait until some of my friends hatch their duck eggs and vent sex them. Thank you!

I think your best bet would be to visit a local breeder or hatchery, have them sex the ducklings for you and pick them up.

The white one is for sure a saxony.
