Silkies get rather clanish sometimes. The right rooster and he has a close knit army to conquer the entire chicken yard.
That actually isn't me being poetic. My first partridge rooster was named Pumpkin because he was orange. He soon had Genghis added to the front of that. He'd lead his hens on an attack of all the large fowl birds. He personally kicked the stuffing out of the ameraucana roosters. Encouraged, his hens would gang up on the brahmas even. It got to the point that all the large fowl would run at the sight of a silkie.
It wasn't until I'd raised roosters separately from the flock that I got rid of the breed aggression that Pumpkin taught.
