I had a small flock and we lost a few. My hen hatched eggs and now we have 2 roosters and 2 hens. I am concerned that as my roosters mature 2 hens will not be enough for 2 roosters. So I am looking to increase my flock. I am concerned about integrating new hens into the mix. Should I add the same breed since they are a docile breed or does it matter and what is the best way to eventually have peace with in the flock.
