I've been raising chickens for eleven years now, since I was ten or eleven years old, and I've definitely never regretted it! In fact, I'm adding on to my already very large coop and getting more enclosures to accommodate my ever-growing flock.
Chickens really do become a way of life, and I would never not want to have at least a few chickens pecking around. Despite the work, costs, and cons of keeping them, 99% of the time (at least) they're very enjoyable to have and be around. Even when I was out shoveling out my chicken house yesterday (and believe me, it was a mess!), all I could think about was how much I love my chickens, what a beautiful day it is, and what additions I want to make to my coop.
As the other posters said, there are ways to deal with the cons, and I think with a small backyard flock many of those cons aren't going to end up being a big concern. Even with my larger flock of thirty-five chickens, three (soon to be five) ducks, and three guinea fowl, the cons aren't all that bothersome.
Ultimately, though, yes, you are asking a bunch of real chicken lovers, you're definitely getting a biased perspective. You should maybe visit some people near you who have chickens, get an idea of what the routine is, see and smell their enclosures, and otherwise investigate so you can make an educated decision yourself. I think you'll find when the actual birds are there, though, it's almost impossible not to love and appreciate them. They have individual personalities, they're beautiful animals, and they're truly fantastic to be around.
I hope you find the right decision for you!
