Sorry for the loss. Did you ever treat for mites? As a rule, I won't go into my hives for an inspection if the temperatures are below 60 degrees. And I never want to get them wet because if colder weather sets in, they will freeze. Did you feed them through the winter with sugar bricks or dry sugar to help them along if their honey stores got used up?
Yes, I had treated the hive for varroa and inspected the hive for winter honey supply, there was more than enough. My pictures don't show it very well but there was still a lot of honey left.
I'm not sure why the frames from the brood box look like they have been in a fire, black and crisp?
I will try again, but I have a lot to learn.
