In addition to some of the comments already posted, I think my pullets feel much safer with the rooster present. I would think that sense of security contributes to their health and happy laying. He checks out everything first, from when I open the coop to let them in the run in the morning, to a new nest box, to any new person entering the area. I don't have a conventional roost right now, and the pullets huddle under the rooster at night as though he were momma hen. Very cute.
He also is quite beautiful, quite the gentleman, gentle to handle, and captivating to watch.
