Don't put the comforter away just yet. It's been snowing here for the last 2 hours. Nothing you're going to do except have a smile on your face the next warm sunny day and bees are out flying again!
It's supposed to be 28 here Wed morning in balmy Alabamy. We've had a few days recently above 80 degrees. Stupid winter weather.......it's supposed to suddenly get down into the low thirties and even the high twenties on one night.
I always cover my hives bottom screens with ply or cardboard if the temp gets below about 40.I have 5 frame mating nucs going right now. The queens should have just emerged. Most are not very well stocked with bees. Yes, I know I should have waited.
What should I do? Wrap with towels? Cover the top and bottom screens with plywood?
I think you'll be the owner of dead hives. You should be feeding them where they are sitting right now.
