I just recently found out I have a male and female duck so I don't know if these are fertilized eggs or not

I think I see possible fertilization in the 3rd pic. It's hard to tell.

A classic fertilized egg will have the white spot on the yolk (the blastoderm from the mother's DNA). If she has had a romantic encounter, the male's DNA will create a bullseye ring around the white dot.

Here's a good photo of what I'm talking about.

Thank you I was thinking the top two didn't look fertilized but I wasn't for sure I'm new to having male and female ducks the female duck I did hatch in my incubator though! My husband works by the water and brought me 3 eggs home we took a chance and put them in 2 didn't make it but my lucky girl did!

So mine are unfertilized correct? I think I removed all my roosters from the bantam pen and she just started laying?

Hmmm. A hen can remain fertilized for up to 30 days after mating. I'm seeing a possible ring around the white speck though it could just be lightning from photo.
