Fertile bantam eggs?

[JollyMonster]

I know how to do the fertile egg check or at least I think I do.
Last February I got some bantam chicks from my local tractor supply. We had a few roosters but the winter got the best of them. I however have 2 leghorn roosters with our 22 hens (14 leghorn hens, 3 black sex links, and 5 bantams) I read that other people had good luck hatching bantam/leghorn crosses so I thought I’d try. The first incubation, I had no luck. No growth in the eggs. My thought was maybe they are to young. I waited about 6 weeks and then I did a crack test to see if the eggs were fertile. They appeared to me that they were so I started collecting. I got nearly 2 dozen. I kept them in a cool dark place. They were slanted and I rotated them twice a day. It is now day 10 of my incubation period I don’t see growth in a single one of my bantam eggs. My temp is at 100 and my humidity is at 45. I have other eggs that are showing growth and look amazing.
What went wrong? Why are only my bantam eggs not showing growth?
The picture that I’ve attached are is two bantam eggs I had planned for my incubator but were cracked when I candled them.

Hi JollyMonster, Sorry your Bantam eggs aren't fertile. Sounds to me like your Bantam size birds are not your roosters cup of tea. It's not uncommon for roosters to have their favorite hens & apparently your Bantams aren't being mated by your 2 roosters. Have you thought about getting a Bantam roo? You might have more success if you do.

The one circled looks fertile to me, the other does too but kinda hard to see.
But I've had even more obviously fertile eggs not develop.
