Peking/Kaki Campbell cross an auto sex breed?

[Peter_Rabbit_Farm]

I bred my ducklings for the first time, and noticed that when I breed my Peking’s and Kaki Campbell together the ducklings had 2 different patterns. I was wondering could the mix be an auto-sex breed.


The duckling with the spot was a hen an the one with the stripes was male .

Here is them older:
