For those that were curious about my dead hives, we were able to go through them on Sunday...
Small, late season trap-out hive - too few bees to sustain through winter, not enough stores.
Large young hive from spring package - made it to the 3rd medium box up. Still had one more full of honey. Little to no pollen. Evidence of brood. Bees present, heads in cells
Large old hive - Still mostly in the 2nd medium box up. PLENTY of honey, little pollen. Evidence of brood. Bees present, heads in cells.
No evidence of wax moths or shb. The small hive did have a mouse or larger pest rip through some wax frames. I'm guessing that the warm snap we had right after New Year's was enough for the queens in the larger hives to start laying. With the eggs present, the cluster wouldn't move away to the honey stores/ran out of pollen, especially when the cold weather returned and they all froze/starved.
I have a few nucs on order for April from my supplier. We are extracting a majority of the honey that was untouched, probably close to 60#. And there's still a full box of honey frames saved for the new bees.
