I think a lot depends on how you'll manage a rooster. Do you have experience with other animals? Are you a dominate type person who doesn't mind making an animal obey you? If you have a dog, does it do what you say? If you have kids, do they do what you say?
I ask these cause lots of folks get roosters and have no idea how to manage them. They're not pets, they're intact male livestock and should be accorded the same respect you'd give a buck goat or a bull. Granted, they're not as big so can't do as much damage, but they can still tear the crap out of your legs. Or eyes out of children.
If you're naturally a dominant personality and have experience with animals, I say go for it. If you're wanting more pets, or have a hard time getting animals or kids to obey you, I'd say skip the roo. You can always add one later, but it's hard to get rid of one you're attached to. Well, until he floggs your child. Then it's easy to do one in lol.
