Hey last week was the ending of the 4 week separation for my two new roosters. I kept them totally separate for 3 weeks then I pulled the diver out from between them so they could see the other hens and roosters when i put them together my black giant faced off with one of them and drew blood on his back so i pulled crow (my black giant) out for a few days were he could see but not get to anyone else. Today I put him back into the run and he faced off with the other new one and got him bleeding from his head. at this moment I have crow in my arms and we are asking. how long do you let them go at it? I take it that blood is normal but when crow gets them to turn and run crow just keeps after them. I didn't let this go more then five min after i saw each of the new ones turn and run but. how long should i let it go. even after i see blood?
