Xerox, sorry you lost a hive. That seems to be a part of beekeeping now a days. I lost a breeder quality hive last Sept, the bees pollinated a garden that was poisoned [thanks Iddee for your text] and varroa finished her off. I had a pile of dead, trembling, quivering, shaking bees in front of the hive, sad!!
Today was 71F so I took the opportunity and quickly inspected the top box of a few hives. One hive has a small cluster, my only hive with a solid black, carni queen. I don?t have much experience with the Carniolean but have been told by several beeks: the carni keep very small winter clusters with explosive spring build up. My point is I may lose this hive, I just don?t know for sure at this time. The hive was treated this year 4 times with OAV, has plenty of honey but like I said, a small cluster. Go figure.
All hives had plenty of stores with at least one hive with eggs and larva. Yea?!?! eggs and larva on December 25th in North Arkansas. Previous week was in the 40F high. Most of my bees were in the bottom section and I did not inspect the bottom deeps.
So, Xerox/we split next spring, make up for your/our loss and we will both have an exciting year for honeybees in 2020.
Enjoy the Holidays,
Van
