Eggspert opinion on this egg?

[Capricoco]

My Guinea fowl started laying not long ago, and I’m not sure if the eggs are fertile or not. I cracked one open and I’m just not sure. Eggspert opinion?

It’s hard for me to tell from the photo, but I don’t think so. I’m assuming you have a male?

Yes. They started laying a month ago so I thought I’d check for fertility. I don’t think it’s fertilized either.
