Re: Mass of dead bees, some honey, zero brood -- what happened, what now?
I could not get the photos to load. But, anytime I hear about piles of dead bees inside the hive, I consider CBPV as one of the causes. High moisture in the hive could have done the girls in too. The lack of brood though makes me think it was a virus. Obligatory question, what treatment protocol did you use? When, what, and how often?
Clean out the hive, store the honey frames and leave only the empty frames in the hive. Swarm season is moving your way quickly. If you catch one, you can give them the honey after they start to brood up.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
