The other thing you're going to run up against when getting bantams is that nobody, with the exception of mypetchicken, sells sexed bantams, so I foresee roosters in your future. You'll have to be able to find a home for them, as I doubt you'll want a crowing bird in your apartment, so picking a popular breed that people might want a rooster of is another consideration you might want to include. If you do settle on d'uccles, mypetchicken sells them sexed, but it's really hard to sex bantams, so you may get a rooster anyway.
