Five roosters and no hens

No wonder the roosters are crowing all the time.

Throw a few hens in with them and they will stop all that crowing.
Why would anyone want to just have roosters in the first place

Roosters are only good for two things....fertilizing eggs and keeping predators away from the hens....that's it nothing else!
Take my hens away from me and I’d crow all the time too.
