Are my duck eggs fertilized?

Doesn't appear to be, did you check egg fertility before you started incubation?

How do you check that? This is my first time trying to incubate eggs

When you crack open an egg there should be two rings. Looks like a bullseye.

Some people keep track of how many fertile eggs they get when they crack the eggs to eat them.

I see a bit of spider veining… yes! This is fertilized! Remember since duck eggs take 28 days sometimes visible veining is hard to see. Best not to toss out any "infertile" looking ones until at least day 10.
