I love my Partridge Rock Roo, he is about a year and a half old and didn't get his spurs in until over a year old. He is very calm, mellow, and actually very quiet compared to my other roosters. He is also respectful to me, his hens, and very sweet with young chicks. I love his personality. Yes, it is stance and feather growth as well as actual comb growth that can indicate a roo. He will try to mate with your silkies, but why is that a bad thing? That would be some adorable chicks (they won't have silky feathering)
