Too young to sex?

[AudreyRangel]

I currently have 8 Blue Swedish ducklings who are 2 weeks old. I ordered them from a hatchery and got 1 male who was marked with a rubber band. As the days past it got too tight and had to be removed. My temporary fix was to polish the male's toenails while I waited to get larger bands. However, once I had the band ready to be put on the polish was gone!!
Is there any way to sex them (other than vent sexing) at this young age?
Thanks!!
