We currently have 18 hens and 2 roosters. All but 3 hens were hatched last spring,The other 15 were mostly raised together. The roosters are Red, and Cogburn. Red matured much earlier. He acted the gentleman and caretaker of the flock, and completely dominated Cogburn. Over the winter Cogburn has continued to grow and mature, and with the weather warming up, both roosters have been feeling frisky. This evening all the chickens (who free range most of the time) were gathering to the barn, and Cogburn saw Red doing his deed and went and knocked him down. Then they fought until they were both bloody but neither one would quit. They seem to be very evenly matched and determined to win. After about 10minutes and they weren't even slowing down, we managed to separate them. We shut Red up but they kept biting at each other through the fence. We locked Cogburn up across the yard. I'm worried about what will happen tomorrow. Does anyone have suggestions? How can I keep them both safe? If they're so evenly matched can I expect they will establish dominance or are they likely to keep up the violence until someone is maimed or killed? Neither one was seriously injured this time, but both were bleeding some. any ideas on how to help them come to a peaceful resolution?
