i missed the bit about it being the only rooster... i think that's much better than a lone silkie hen. I'd still be likely get a silkie hen for him too, though. My real problem with a lone silkie hen came from my gold laced wyandottes. Black star bantams sound really cute, I love the look of the barred rock bantams, like a perfect little miniature. Those would be fun crosses for your bator, you wouldn't have any silkies in the first generation but in the second you would have 25% silkies. barred silkies would be awesome too.
