I started with Belgian d'Uccles and Silkies from a neighbor, and found that the Silkies weren't for me, but love the d'Uccles! Since then, I have many standard sized chickens of several breeds, and still d'Uccles, and now also bantam Easter Eggers. They all get along, including roosters.
The one downside of bantams, if free ranging, is that they are more often taken by hawks.
Other predators are happy to take standard birds too; everyone loves chicken!
For your first flock next year, look at Henderson's breed chart, and several catalogs, and order a few birds that look interesting, and will be fine in your climate.
It's about trying some, deciding that you like this one over that one, and moving on with new choices. I've had birds that 'everyone loves' and sounded good, and disliked them. Then, birds that didn't look interesting, and worked out great.
