The boss bird of my hen yard flock definitely knows what Silkies are. The only other cock bird in there is a Silkie. He's nearly the size of some of the smaller dual-purpose hens and whenever he thinks he can get away with it he'll try to jump one. Try anyway. Most of the girls won't put up with his nonsense, but I've seen him score a few times. If Hopalong is anywhere near though he'll run him off no different than he would any other interloping rooster.
Most of the times the big hens would ignore the Silkie hens unless they got in the way while they were feeding. Then they'd get a peck.
