I went to put a fondant patty on my hive and found a the majority of the girls dead. They were mainly on the bottom board or on the perimeter of the boxes. There were a handful of live bees. I didn't go through hive thoroughly, but it did look like there was some moldy areas around some clusters of dead bees around the perimeter. They looked good going into winter - lots of honey, did a mite treatment in August. Any ideas?
Condensation? The winter weather has been all over the place in Eastern PA - cold, rainy, a bit of snow, today in the mid 60s.
