The protection a rooster offers is often misunderstood by keepers. The rooster is there to give warning calls, preferably soon enough that the group has enough time to hide. A rooster that throws himself at every threat will soon become a dead rooster, and leave behind a group that's used to being warned by him at a greater risk of an attack.
A keeper that lets their birds free range but expects the latter from their rooster will often be disappointed with the outcome. I'll be the first to say that a rooster's value in a free ranging group is immeasurable. Still, attacking every predator is not one of those needed qualities.
Seeing that the birds here free range, my first priority is them. Managing certain behavioural issues comes a lot easier given their territories. As long as the males treat the hens, pullets and chicks as they should (and there is room for them), I can work with males that don't particularly like me. In my experience, there's really no point in looking for a male that respects you, simply because that can mean something drastically different to each person.
I tend to believe that if there is some understanding (mostly on my part, since I am the foreigner in their space), we can make it work. Lots of different personalities of males come through here, and while some are much easier to deal with than others, as long as they take care of their group, there's a reason for them to stay.
