If I dont see a rooster mate in front of me, I am going to assume he is not doing his job that he is there for and I am going to find one who will. Thats HIS job and he better be doing it whenever he needs to. If I see a male who is not actively trying to breed hens I am thinking his vigor is not that good and will either not get chicks from him or they wont be as strong as they would be from a more vigorous male.
Just dont see the point in stopping them, that is what they are there for. They dont have feelings, its not a dominance thing. Its a he better get the job done or he is gone thing......
Sorry I am old fashioned and have raised thousands of birds over the years and this seems nonsensical to me.
Some males fight simply because they want to. I have had some wonderful, playful males over the years and have had downright devils who would tag you anytime they could. I have been pecked by males alot more than I have ever been flogged. Those beaks can draw blood in a hurry....
