I rooster is helpful especially with hawks. A rooster's job, besides reproducing, is to protect the flock. When you watch a flock of hens with a rooster the hens heads are always down looking for something to eat while the rooster spends a lot of time watching.
Therefore, there hawk warning calls can give the hens a running start for cover. One thing I have noticed over the years is that some roosters "cry wolf" too often and then the hens have a tendancy to ignore him after a while. I had one rooster that would give the warning call for pigeons, crows and other such birds.
When I lived on 40 acres I had a very large flock of free range chickens with numerous roosters and the roosters especially those raised together will banned together and fend off predators such as a fox or smaller dog and go after hawks that are on the ground. I seen it many times with my large flock. It's intimidation by numbers. However, with a predator like a coyote are large dogs the roosters can only warn of the danger and like the one poster said run interference for the hens. They will actually try to lure the predator in their direction much like a bird does with the broken wing act.
