I have put a lot of roosters in my separation pen, best thing ever, the most recent rooster went in there in May for hen harassment, and was just recently released, he is very respectful and is able to hold his own against the other roosters. I will pen them until I feel comfortable they have gotten their heads on straight, months, releasing occasionally to see if he's improved, so round that boy up.
Here's a few photos of my pen, I've kept two large fowl, or three bantam roosters in it at a time, this guy had it to himself.
