Okay. I'll try and see if we can try that a few times. Where we live I let my kids play outside while I cook or something and check on them every few. Lately I don't let them unless I'm out with them bc of him. I'll talk to hubby and see what he wants to do. I'd prefer roo to go but we'll see. My husband was saying he wants to pen them up again.
Seperating the rooster from his harem should bring down his hormones. We often separate roosters in bachelor pens, but we have to do it because we breed chickens. In a backyard settings why would you keep a rooster, if you have to cage him away from the flock? I agree with @Acre4Me that you should get rid of that mean rooster. Meanness is also inheritable, you don't want the next generation to be mean too.
