I have a roo that is somewhat like yours, it took my 6 year old grand daughter to put him in his place. For about a week after I got him, he would run her out of the chicken yard. One day I saw her headed to the chicken yard with a stick in her hand. When I asked her about the stick, she said it was time to teach Little Red some manners. As she entered the yard, the roo came a running, just as he was about to put the spurs to her, she held up the stick and yelled. This stopped him in his tracks, but he kept eyeing her as she checked the coops and collected some eggs. As she was coming back toward the gate, he figured it was his time. Little did he know she was watching him and just as he jumped up she let him have it. She had to do this a few more times, but now they are best of friends. He still gets me from time to time when my back is turned. For each roo you should have at between 8 and 15 hens. He will in time over work the one you now have.
