We had chickens in the 'burbs before. Well, my dad did, when I was younger and still at home. They do require some work, it's not like getting a cat. They will need shelter, and a chicken coop requires cleaning. They will also need protection from predators. Despite ours having an enclosed, heated coop for shelter, inside of a larger, fenced/chicken wire pen (like 50ftx20ft), ours were eventually eaten by a wild animal. It was sad, because they do become pets.
If you do end up going for it, do some research first. Make sure it's legal where you live. And do not get a rooster - ours was noisy and there was some fighting with the hens. We had to give our rooster away.
On the upside, they do eat just about anything - we added leftovers, vegetable scraps, pretty much anything with their regular food and they loved it. If you have 3 or so hens, they will provide enough eggs for a normal family, and possibly more.
