.... that I'm obsessed with owning chickens?
It's true. My idea of heaven is a town house in Brooklyn with bees on the roof and chickens in the yard.
It's actually more common than you would think and organizations like Just Food raise money so that they can donate chickens (and training) to a couple community gardens and schools every year. It's called the City Chicken Project and you can read about it here.
Chickens only need three to four square feet of space each so you can have two chickens in an 8'x8' coop! (They also need access to the outside so they can scratch and hunt for bugs.) Most chickens lay eggs two out of every three days so you'd have a constant fresh supply!
Here are answers to a lot of questions about raising chickens in the city.
