I have five Speckled Sussex (two months old) and six Buff Orpingtons (6 weeks old), and it turns out two of the Speckled Sussex are roosters. I'm hoping they will be able to work out a pecking order so everyone can co-exist but this is my first time with chickens and I'm a bit apprehensive. I'm sure this is dependent on the roos individual personalities, but do others have experience with two roosters in a small flock? Is there some minimum ratio of hens to roosters that it takes to keep everyone happy?
