If you are in Vermont, I'd nix the wire floor idea UNLESS your hutch is located inside another structure like a barn. You will need a coop large enough to hold your birds through storms and bad weather, etc. A hutch won't be large enough, and the wire floor will freeze their feet and/or let in too much wind and drafts in the bitter cold of winter.
I think wire floor coops are great IF:
-You live in a warm climate where you don't have many really cold days
-Your chickens won't ever have to be locked in the coop for any reason (cold, bad weather, etc)
-Your coop is raised. (just don't see the point for wire floors otherwise)
I have wire floors and love them, but I live in NC where it's a rare day that gets below 30 degrees, even in winter. AND my girls only go in the coop to sleep - they aren't walking around in there on the wire floor. They just go in to lay eggs and to roost.
