The chickens also make the "land predator" sound when this guy comes around. He's... done some ****ed up things to them, after which he puts them back. (It's an ongoing case.) Would a laidback (we're getting an australorp this weekend) rooster go after someone the hens identify as a threat?
Sorry to hear about your problems As Beer Can said, a game cam to collect evidence will help, especially if you have an open case against him. And if you get an aggressive rooster, as Beer Can also pointed out, they don't just attack some people, they attack ALL people.
I would suggest an LGD but I see you are allergic, unfortunately.
Emus are on my wishlist, too. I'll be hatching my own when I am ready for them.
Guineas shouldn't be too expensive, at least not any more than chickens are. But they are loud, so if you have close neighbors that might be a problem.
A Black Australorp rooster that's laid back towards people probably won't attack a human bothering the hens. I have some hens that don't like to be picked up and scream bloody murder and make the "I'm being killed" sound when I grab them. All my roosters just ignore it.
Can you perhaps do something like a fully enclosed run and just keep them locked in with a padlock when you aren't around? That way he'd have no access to them whatsoever.
