Duck eggs not fertile but duck is with a drake?

[Kennas_Kritters]

I have a Pekin hen with a khaki Campbell drake. I have seen them breed multiple times but none of her eggs are fertile. She has layed over 30 eggs and none have been fertile. She turned 6 months a few months ago and the drake is over a year old. Why wouldn't her eggs be fertile?

I had this happen with my first two ducks
Also pekin hen and khaki drake
Give it another month or two
But I learned the hard way when I Finally got fertile eggs that her eggs were still small and I had to assist all but 2 babies who were the bigger of the eggs
Now I don’t incubate anything under 70 grams and have hardly any issues
They will also be sex linked at birth
The dark ones are boys and chocolate brown are girls

Didn't even know sex linked ducks were a thing. Lol. Do you by chance have pictures of them as adults? Curious what they look like when grown. I'll give them another few months. Hopefully I'll get some fertile ones soon!
