Hives that were lost were lost due to starvation and/or cold. Still, I was able to pull two full boxes of honey frames off the dead hives, so there was plenty of food in them. Hopefully, we'll get the last hive through to spring. I have a full box of honey on top of the hive that hasn't been touched, and added a winter patty today as well.
Here, at 42 degrees, the bees are out enjoying the sunshine, getting drinks from melting snow and pooping!
