Ok, we've figured out how to rig up a bachelor pad. I will do my best to give them some security but we don't have the resources to build another FortKnox coop.
After putting up with two aggressive roosters in our lives, I'm now saying that the first sign of aggression toward me and the rooster has to go. I can't live in fear again. I notice when the current cockerels size me up I get nervous. I'm not letting on, at least not knowingly, but I'm just not going to put up with actual aggression again.
It's the constant harassment of the hens that has me so worried. It's markedly altered their behavior in very negative ways.
