Wyandottes
Rhode Island Reds
Speckled Sussex
Welsummer
Marans
White and barred Rocks
California Whites
Leghorns
Jersey Giant
Polish
Cornish
Orpington
EEs
Cornish cross
And feral barnyard mixes
These are all the breeds I've raised here. My top three are Polish, Jersey Giant, and speckled Sussex.
I would actually recommend ducks over chickens though, they really take all of this weather quite well. Heat, cold, rain and wind don't make them quit laying, they also have great disease resistance.
Edit: Just saw that you already have ducks, they do great here!
