They do fine in the north, there's a couple of breeders in PA and one in MN. I think one of the best used to live up in MA. As long as you give them adequate shelter in the harsh weather, they do great. They make great broodies when allowed. I've not tried a cross species brood though, so I don't know anything about that.
There's a breed page on byc and one at the ultimate fowl wiki. Both give great information regarding the breed.
