I received my NWC queen a few weeks ago via overnight shipping, and she appears very nicely-mated. She's quite plump, and her brood pattern is nice and tight. My first bees are to emerge within days, and eventually replace my Italians in the hive fully. Time will tell how well the Carniolans will carry through the winter. I am giving five stars based on what I know and see in the hive so far.
