After dawn, and after the hive heater went off: -5° outside, 22° in top of hive.
At dawn, today: 7° outside, 32° at the top of the hive.
After the heater went off: 5° outside, 31° at the top of the hive.
Since the bees have not been pushing any carcasses out of the hive entrance, I removed the entrance reducer, and looked inside the opening, to be sure that it was not clogged with dead bees.
No dead bees at all.
After the first night with the hive wrapped…
At dawn (hive heater still on):
Outside temp = 1°
Temp inside top of hive = 53°
Just after dark, I wrapped the hive with two old blankets and a painting tarp with the plastic side out. The temp inside the top of the hive was 39° when I wrapped the hive (the outside temp was 15°), but it warmed up to 41° within an hour. The hive heater was on throughout this time.
Just before dawn this morning it was 0° outside and just 30° inside the top of the hive. Later in the day it was around 25° outside and 45° inside the hive.
I added optional upper entrances to 7 hive boxes. The holes are 5/8″ as per Tony Bees (a post in honeybeesuite.com). The landing boards are made of 5-gallon paint stir sticks and are 3″ long.
After a sunny day when a few of the bees were flying, we get this.
Sunny and 54° at noon. A few bees out and about.
Partly to mostly sunny. Still and 54°.
The bees were doing a little bit of housekeeping; removing dead bees from the hive. I arrived after the sun was off the hive, however, and didn’t see any of them flying.
This photo is from right in front of the hive, and captures just about all of the dead bees that were out there.
