Yes I only have the one Roo. He is a lot larger than my silkie hens and the more I have been observing them I have noticed that he seems to prefer the larger ladies of the coop ( brahmas, cochins, svarthona, Americaunas ) lol. The incubator I am using is a Hovabator.
Heres advice and a trick to test it.
First, to much butt fluff can interfere, it has with me, so do try trimming.
Next, if your ok with it, crack open an egg, if you see a large bullseye, it is fertile. You will see a small “bullseye” (more like a dot) either way, but it should be noticeable. This narrows it down to being a problem like from incubation.
Also, please turn your eggs if you let them sit so it doesn’t cause deformities or hatching problems. Average sitting time for counter/fridge is 2 wks but can go passed that. The more days go by and it slowly lessens the chance of the eggs hatching.
You could make a breeding pen with him and the other silkies to insure he mates them temporarily or permanently.
