Infertile chicken??

[KatsHerd]

Need some opinions on this one.
We have a speckled sussex hen who is about 8-10 months (assuming seller was honest), shes been with the flock for over 3 months, she is a successful layer, lays almost daily, she is a welcome part of the flock & has established pecking order. The rooster is a successful breeder, its definitely not him. She allows him to mount her & we haven't noticed any issues in that department.
However, this is now the 2nd month I've attempted to incubate her eggs & every single one is a no go. Every egg of hers that I crack does not have a fertile ring, I just chuck a few of hers into incubators when I'm hatching in hopes I'll get a lucky egg. I'd absolutely love to get little minis of her.
What are your thoughts?

She may be rejecting his sperm.

I've heard of this with low ranking roosters, but he's the only rooster on our farm that isn't under 8 weeks old haha

Doesn't mean she thinks he's worthy... it's a possibility.
