Welcome welcome!!!! I have 4 roosters and i have them all separated. My oldest roo is a Minorca. He is fine around young roos but as soon as they start to crow.....no more mister nice rooster. He stomps his feed and has a fit. My silkie roo(s) could care less, don't think they can even see the other roos. All my silkies are still together with all my other breed chicks and they don't seem to care about each other and get along pretty well. I think that if they grew up together they might be ok. Once they reach sexual maturity there will be a pecking order established. I have seen and read about roosters living fine together....as long as there are plenty of girls to go around. That is my second bit of advice, make sure you have plenty of girls to go around. All roos think about is girls and you will end up with a bunch of featherless hens if there are not enough.
All my roosters are very friendly to me....they don't like to be handled but they don't attack.
