I've read through the whole thread, and didn't see any mention by the OP that they have roosters already,
If you have the choice, pick a heavy breed, as they're more likely to be calm. Even so, you need to raise them to trust you, and that means calm behavior around them from the time they're babies. Don't do anything to scare them, such as snatch them up from above. Always approach any chick from the side, slowly.
As a rooster gets his hormones, between five and six months, he's at his touchiest. It's especially important not to make sudden or loud movements or startle him. Approach all the hens in a like manner, and avoid making any hen upset in front of the rooster. Whether you handle the roo or not, isn't as important as not doing anything to make him fear you or distrust you. Any discipline needs to be done in a firm, slow, deliberate and calm manner, such as holding him down with his head on the ground when he makes an aggressive move. But then you need to examine what it was YOU did that caused him not to trust you.
