I went out today and listened with my stethoscope - nothing
So then I looked inside the window - frozen bees
Since it looked futile, I went ahead and opened the top of the hive - and again, just ice inside the hive and dead bees.
I suppose there could be a tiny core of bees in the middle of the comb/honey that have survived but probably not enough mass to make it.
When it gets warm this spring, I will really look by pulling up the boxes, but I'm going to order my packages NOW!!
