I have had a few banties in my life here, still have two in the flock. Banties are nice, once they settle down, but when they're juvies, boy do they fly. High, high up in trees. You may not have this problem since you seem more city like and likely have an enclosed shelter, but out here in the woods, those banties are a pain for a few months until they realize they're supposed to sleep in the coop, not in a tree. I even taught guineas that.
I also have ducks. I started with small mallard/call crosses which flew away in fall. They never came back so I assume they didn't make it. Then I got giant pekins, they are way too fat to fly. I got the pekins and some other large ducks from Al's Quackery which I think is down by Saco area. I also have hatched some ducks here, and refilled using
TSC ducklings as well. The only pain for ducks in the winter is they splash water all over the place and then it freezes and makes a dangerous mess to walk over. The other months of the year they make lovely mud for you to walk in. Their poop water is loved by my plants. Not to anthropomorphize too much but of all the fowl I have, ducks seem to be the happiest. They just really seem to enjoy life.
I have found that of my chickens, the ones that seem to mind the cold the least are the ones you'd least expect. The banties, the leghorns, the naked necks seem to just accept the cold and move on. Other large fowl non feather footed breeds seem fine with it but less brave coming outdoors in it. The giant wimps have been my large fowl with feathered feet. They refuse to come outside in the snow. They got nasty gross in the mud. I have a few with feathered feet left, including a showgirl that had to get in my kitchen sink last week and then get a blow dry due to the mud from the thaw followed by the deep freeze... all over her heiney.
I guess the point is, that you can pretty much raise most fowl here, as long as you have a good coop that they can get in to get out of the nasty cold. If you have a coop that's drafty or 3 sided, then you're going to need to be careful about what breeds you have.
