We play punt the rooster. They fight with their feet, so it makes sense to them. And I am bigger and badder so its never something that needs to be hashed out a second time. I just make a ruckus, chase him around and scoop and toss him with my foot. No bodily harm, just a little quick learned humility.
I even pick up my toddler under his arms and chase the rooster around swinging the kid at him. That was Mr. rooster understands he's at the bottom, even below the kids.
Its something we've never had an issue with. The first time one of the roosters makes direct eye contact, or comes inside our personal space thats my reaction. Its never something they try again.
