12.5 degrees today, all but one of the main colonies were out flying. I checked the floor for dead bees in number 2, not sure there was enough to block the entrance but still there was quite a few, cleared floor.
The small nuc I have had a lot of bees around the entrance. So I moved it's frames to another nuc box. There was a lot of dead bees in the box. It does not have a lot of bees now but it is alive.
