I forgot to add to my first post that if your roosters don't understand that you are the human and you are dominant over them (not the dominant rooster because you are not a rooster and they know that) then they need to be invited for dinner. A smart rooster will understand that his human is the bringer of the food and treats, and every other good thing in his life. When you start training them at a young age - the whole walking through them, standing up to challenges, etc. - and they still don't get it, you don't want to keep those genetics going. Find a smart one and let him breed your hens.
