I asked before but I will ask again, How do you know your eggs are fertile?
I have some crosses that the roosters look similar to that. The hens also look similar. Look for neck feathers that are narrow and highly shiny. Also look for spur buds, although I have a hen with spurs too, it isn't very common. Hens will also tend to have fluffier back feathers just before the tail and rounder kinder eyes.
You may be missing them because they are tiny. The little bump on their legs that they have at hatchingI have found that most of my hens have no spur buds and we have many breeds. Only one of our hens has had spur buds beyond chicken stage and she now actually has spurs. It is a cuckoo maran.
