I just went to the hives opened the entrance and pulled the dead out (I have SBB's)
I do this occasionally to check the death rate, especially after a cold snap.
The "slide-out board" (i don't know what to call it) looked normal w/low mite count.
I peeked under the outer cover hive#1 there were some in the inner cover center hole.
But hive #2 it was full of bees spread out filling the entire space between the outer an inner cover.
Sounds like there are still a ton of bees in there, I left them about 80-90 lbs honey.
It's very sunny out but in the 20's should I be concerned?
What signs do you watch for to know if their stores are low, are there any "hunger test" methods??
