If I didn't live in the city I'd probabley have a small coop with a few hens and a rooster, I think they're great as a family pet. Geese or a tom turkey are a good idea for some extra protection in the coop... but I also don't want them for that reason, they're nasty tempered big birds and just not fun, lol.
Chickens are very low maintenance, just a bit smelly so you keep them out back in a corner where you can keep an eye on the coop but don't have to smell it. Give em a place to keep warm, dry and safe, give them a little food and water everyday, let them out to wander around your yard and garden to eat all the bugs now and then. And with the right number on a good rotation, fresh eggs every morning (and there is NOTHING like good fresh eggs, if you love eggs then chicken raising might be your fastest track to living fatter and happier). Only downside to them is they are pretty vulnerable birds to many hungry critters, and the other usual supporting a dependent living creature things: like finding some hay to lay down in the coop/pen and shoveling out the old smelly sh!@ a couple times a year, throwing some feed and water in a couple bowls daily, etc..
