brrrrrrr, 10 degrees out and 6 inches of snow.
I have one weak hive (2 frames of bees, had a drone laying queen late in the year, and took a while to get the hive queen right) in the basement as a learning experience/trying to get them built up. I think all of the others outside are in good shape.
I am going to have to babysit my basement hive, but I am sort of looking at it as a learning experience and they would not make it on their own outside.
