we got 10 young silkies this summer, they were about 2 months old. they were not sexed. about 3 weeks ago, out of the blue one morning, after coming out of the coop, 4 of the silkies started having a crowing competition!! up until that point i was pretty sure 2 were roos, but being new at this whole chicken thing i really wasn't sure yet. sure enough, 4 of them were crowing up a storm that day... and now this morning, a 5th one is crowing should i be concerned?? everyone gets along, no one ever fights. but could it be that as they are now reaching maturity they might start to have issues? i really want to keep them all, i have already had to give away a bantam rooster a few weeks ago and it broke my heart. we also have 14 standard heritage breed chickens in the same coop, including 2 roosters. they all get along, haven't had any issues. big chickens and silkies mostly stick to their respective gangs. any insight would be appreciated!!
