We have roosters because, people keep giving us free roosters! If you want to pick up a free rooster, in Northern Indiana,I'll give you one! If you don't want to commit to rooster ownership, I bet we could find somebody near you who will loan you one, so you can find out if you like having one.
The big advantage is a good roo will stand between your girls and predators. He is the first line of defense. I want to hatch my own chicks and I'm not interested in paying a lot of money for hatching eggs so for me, having a roo around at least part of the time is a no brainier.
Possible disadvantages...
The crowing... Turns out we like it and the neighbors have never complained.
Roosters are sometimes rough on the girls! Even the polite ones are a little rough.
Start with a mature roo if you can find one. If you get one who isn't polite house him separately for a while. Not being with the flock can teach some of them manners in a hurry.
My advice
Try it without for a while then try it with. See what works for you.
