Hi, I have 15 chickens, 2 of which turned out to be roos. I have heard there should only be 1 roo per 10 hens. Should I get rid of one? If I do get rid of the more dominant, rough rooster will the other one become dominant and rough? This is my first flock and they're only 5 months old so this is all new to me. Not sure what to do. Any suggestions?
