unfertilized eggs

[PeaBee]

Hi folks, does anyone have any idea why eggs from a 6 year old Emerald Spalding hen were laid unfertilized?
I only added them to my group about a year ago, with 2 roosters and another 3 hens.
In the same aviary I have a 2 year old peach hen with the same problem, she is still young so I can understand it, maybe it will work for her next year. peaches are a bit slower.
Have any of you ever had the same problem?
Greeting from Austria!

Have you seen any mating?

Not really!
My bronze hen had laid fertilized eggs and I have not been able to observe them even once this year.
it's possible she didn't like the roosters?

Yes. She may have been added too late in the season to get adjusted to the environment and the cock. They take time to bond, not like chickens.

I agree she probably got added to late and is not comfortable enough with the male to start mating with him.
