I have 1 buff rooster, 4 buff hens, 2 leghorn rooster, 2 leghorn hens and 5 plymouth rock hens. So, 3 roosters to 11 hens. Is that too many roosters? The leghorns are all 10 months old and all the rest are a year old. The roosters have been fighting a lot over the last couple of months. Blood baths a few times. The buff rooster never seems to have a drop of blood or even a scratch on him, hes the biggest. Do I need to thin down the rooster population?
