I have 9 week old d'uccles. Yesterday several of the little roos kept fighting. They weren't just chest bumping, they drew blood. A couple of combs were bleeding and you could see where they were pecking each other around the eyes! I tried removing the one that I thought was instigating the fights, but then another one would take over. I kept separating them and scolding them and eventually they settled down and stopped. Do they usually start fighting this young? They are a little small to start eating them.
