Quote: Well, that may be true in most cases. Most roosters will try to fight if they can't get away with the hens; most will lose their lives doing it, however, I know of one rooster in the link I posted above who has fought off several predators in "beak to paw combat" and still lives. Yes, he is quite exceptional, having lived through coyote, fox and dog attacks- he does make a case for having a rooster for a free ranging situation.
I consider my roosters my first line of defense-that does not mean I expect them to literally fight off a predator, but it does mean they will alert the flock to danger, would be between the hens and the danger and, even at the loss of their own lives, hopefully, save most of the hens. That is what they are here for, even moreso than producing chicks.
Of course, you don't have to have a rooster if you don't particularly want one. I have one hen who is the first to alarm about anything in the skies. She is not the most vigorous forager, so she sees everything that passes through the trees. I always say if we didn't have a rooster, she'd be the one watching out for the others. The other hens don't seem to listen to her like they do the roosters, though.
