I have a mean rooster and i need to get rid of him. He is a beautiful bird but he is just to mean to my roo Roockie. I have a hen i want to breed him with first. They are in the same pen but there is also another roo in there with them. Im going to put them two together in a seperate kennel but how long do i need to keep him with her to make sure her eggs are fertile by him. I have seen him on her a week ago or so but i just what to make sure the other roo didnt get her to.
