It this egg fertilized? Didn't think I had a rooster.

I don't see any boys in there, not even any I'd want a better photo on. That does look like a bull's eye me, how many of those are you getting?

I'll include a link to an article that talks about parthenogenesis which could explain that, but that is pretty rare.

Parthenogenesis: Embryonic development in unfertilized eggs may impact normal fertilization and embryonic mortality | The Poultry Site

How interesting. Thanks for sharing this article. It was a very fascinating read.

Your hens just tricked you.
