Check the hives the other day.
The swarm hive survived, small but survived. It has insulation on 3 sides and inside the top cover. 1 medium for bees, 1 medium with 3 frames on each side and a sugar block on top of the frames.
The Calif package died, looks like they starved. I had 3 mediums with a spacer and sugar block on top. The sugar block was hardly eaten, it was probably too far away from the ball of bees. It had insulation on 4 sides and the cover.
I will not order any more California packages, they cannot survive the winters here.
