Everyone has different opinions on the thought of keeping roosters. It's actually a large topic that often binds conversations with disagreeance... albeit that- you're free to follow up on what works most for you. Like everybody, we have our own ideas of keeping a healthy flock.
Roosters, IMO, have mutiple jobs for being part of the flock but sometimes can be cons too. If a fox had entered the run to fetch some dinner... doubtfully would the rooster stop him. He may try to fight or scare the predator away from his hens, but chances are that the fox ought to win.
Granted this scenario is a thorn in your plan, the rooster
can warn the flock's owner. Whether it's crowing for you to hear or distracting the fox so the hens have time to escape, he may just save the egg layer's life.
That's job #1 for Mr. Rooster. But there's plenty more.
A rooster can always be breeding stock. You may not be in the mood this Spring or the next to hatch some chicks -but let's say something happened to your flock or they stopped laying- you can always have a costless backup plan.
And my last job for Mr. Rooster is the idea of them being a protective, handsome, sometimes very appreciative of their owner, creature.
So- instead of culling the innocent roos that belong to your flock... consider rehoming them by putting them up on Craigslist or giving to a close friend, or consider saving one of them as a flock-mate.
There's different ideas that may work for you and your flock. Which one has a better personality towards you and the hens? That may just be your flock's next protector.
To me, a rooster can comfort the hens depending on their disposition. They are taken for granted and certainly underrated when really can be wonderful for you.
Also, I've owned this very friendly Orpington rooster in the past, Rusty, in fact. They are good birds and I wouldn't trade the hens for the world. Sophia, the first hen I ever owned in which is still with me, is like a friend too.
Best of luck and God bless! Sorry for ranting- I'm hoping my words may just to justice for your perspective.
