I have a young 20 week old silky which I'm pretty sure it's a roo! No eggs/crowing yet, but has very strong roo characteristics. So the other day my BSL roo that he grew up with, (who is already mating my other hens and much larger than everybody) mated with my silky roo ,and the silky squatted and let him mate. Is this common in less dominant/smaller roos? I'm confused.
