Okay but isn't it a waste of money on food and care? And a waste of space? Business wise..
If you had an egg laying business or something like that I might say yes but lots of people just have chickens for pets so in that case, no. Although even if you had a business, roosters can be excellent protectors and very valuable. I've read stories where the roosters all teamed up and herded the girls to safety and also formed a wall, something that couldn't be done with one rooster. So I guess it depends on why you have chickens and your philosophies on pets etc. Cause most dogs and cats don't do any work either and eat up feed so why is a rooster different? IF you have it for that purpose (pets). Cause I know some people don't have pet dogs and cats either and think every animal should have a job, which is fine, but I guess it just depends on your outlook. Sorry for the novel haha
Also I just realized, even if people maybe make the cats and dogs work or don't have them, some also have parrots, etc. And they're really the same as a rooster, eat a lot and don't contribute anything, except roosters are a bit bigger
