I have 2 roos hatched at the same time about 5-6 months ago. They are both very obnoxious to the hens so they have been segregated from the rest of the chickens in a "bachelor run/coop". They have been living together fine for the past three months. But, 3 days ago they started fighting. (It was almost a full moon)I let one roo out of the run but he stays on the outside of the the bachelor run. They have been trying to fight each other thru the fence. Even yesterday when it poured rain all day the one roo stayed in the pouring rain on the other side of the fence beside the other roo. It appears they have stopped fighting but I'm afraid they will start again if I put the roo back in. Suggestions?
