We have more roosters than I ever would have kept because they are grandfathered against the code change that now bans roosters. I had planned to sell off roosters but now we have multiple roosters in case something were to happen to one. Normally we would keep hens and sell roosters, swapping out the rooster every year, but we had to sell hens and keep the roosters instead. Having more than one rooster breeding together does help mix up the genetics a bit more in case people get a straight run of chicks and keep a rooster for breeding the hens (less likely to be full brother and sister but still possible). Most people know to sell off the roosters (or eat them) and bring in an unrelated rooster for breeding or they just keep hens for eggs.
Our roosters crow but it is not too annoying. I like barnyard sounds over people noise but not everyone feels the way I do. We may decide not to have roosters in the future but we hatch to cover our feed costs so they are necessary for now. If we could just hatch ducks or maybe quail to cover feed costs for layers then we could do away with the roosters but I enjoy preserving heritage breeds and making purebred birds available. So many people with roosters have barnyard mixes rather than breeding with purpose and intent.
