Why I have a rooster:
- Breeding
- Eye candy
- I like to hear them crow
- They're helpful with integration of chicks. I've seen the little ones using the rooster as a pick when a hen was chasing them -- running right underneath their father to escape.
- I was surprised by the many ways my boy(s) acted as leaders once they matured into flockmasters. Even things like putting the flock to roost at the proper time instead of me having to round latestayers up at dusk.
I have no confidence in the "protector" aspect other than possibly as an alarm, but though the flock was not rowdy before the males matured, they are particularly orderly and peaceful with a mature flockmaster.
Note: I have not had a bad rooster yet. Bad ones can be absolute nightmares. I attribute this to a combination of following good advice from experience people, my breed choices (males have been a Light Brahma, a Black Langshan, and a Blue Australorp -- all breeds noted for laid-back males), my own natural ability at dominance with many kinds of animals that lets them know from day one that I stand no nonsense and that I'm willing to eat troublemakers, and a heaping helping of GOOD LUCK.
Since you're new, some of the good advice that I've followed is this:
Have a hen-only flock the first year then let mature hens raise up the males with good chicken manners. Not beat up on them and put them in fear, but teach them their place in chicken society so that they don't become bullies as hatchmate cockerels might if there are no adults to show them how a good chicken is supposed to behave.
