Since you asked it’s not a dumb question. If you don’t know the answer and it has value for you, not asking would be dumb. We all have to start somewhere.
Breeds are a manmade thing, nothing natural about them. Chickens don’t care about breed. Any rooster will try to mate any hen. If your Silkie is a bantam he may have trouble doing everything right and hitting the target, but most bantams manage quite well, thank you, even on full sized hens.
The gene that gives the Silkie type feathers is a recessive gene. That means it will not show up in the first generation. But things like that head shape could show up, at least in part. You could get some interesting chicks.
I don’t know what your goals are for those chicks. Chicken genetics can get pretty messy when you start crosses like that, you don’t always know exactly what you will get. But traits like behavior and egg laying are pretty much inherited. You should get chicks that are somewhere between your hens and the rooster. The traits might be closer to one parent than the other but should be somewhere in between.
