I currently have 2 Cockerels, Elvis & Jerry Lee, though it was not on purpose. One of my pullets turned out to be a cockerel (Jerry). Although my 2 boys grew up together, I had to separate them because they did not get along. The dominant one, Elvis (black copper marans) constantly chased and tried to fight the other cockerel Jerry (game), so Jerry was placed in a temporary cage while the Elvis gets to stay with the hens. As soon as I have a second run built, Jerry will get his own flock of girls. I'm also considering a third flock with another rooster.
Having more than 1 roo has pros & cons. I love to see the different colors & temperaments, not to mention the unique crow each roo has. My pen is far enough away from the house that they don't wake me up in the mornings. I also agree with some previous posters, that it's good to have a back-up, as well as variety (if you plan to hatch out chicks). That being said, I don't think there's anything wrong with having just one rooster either. It all depends on your preference, as well as the circumstances.
