Before a cockerel or rooster even thinks of being aggressive, it’s our job to constantly communicate to him that he is subordinate, by controlling the space and making him get out of our way. If you observe your chickens, you’ll see that those lower in the pecking order naturally move out of the way when the more dominant chickens approach. Walking toward your rooster and making him get out of your way whenever you’re in the chicken yard helps keep him subordinate from the get-go.
