I got around to everything the last couple days. 10 locations, 130 hives. 30% loss at this point. Survivor queens 35%loss vs southern 50% loss. Purdue 58% loss....however some started late. Everything was treated for mites in August except Purdue. The treatment, thymol (ApiGard), was just intended to be quick and knock down phoretic mites. Mites within capped brood could become a problem later, especially with extended brood rearing.
Worst yard was at home. 60%loss. Against my better judgement, I consolidated all the hives to a tight location by the barn and fenced it for wind. Normally, they don't get to fly so much in Nov-Dec. I feel many of the forage bees either got disoriented or got teased into my stack of wet supers and didn't make it home. This resulted in clusters too small to keep warm. It was the only yard I saw that bad.
Several yards with very low losses....10-20%.
Most losses were dwindled colonies or starvation.
Dwindle likely due to either mites and/or loss of older bees too soon because of warm weather. Often a tiny cluster, with small amount of capped brood (capped brood indication there were enough bees when the eggs were laid) and ample honey.
Starvation in some was because they used everything within reach for brood production. Some were dead on one side, with full frames on the other side... they don't like to move sideways.
Many of the live hives are full with bees, but low on spare food. Added boxes of honey from dead-outs.
I did not break frames loose... no need to break the clusters any more than to take inner cover off and just add to the top. Yes, a little smoke helps to keep them from flying too much.
I'd recommend feeding very heavy syrup or candy boards if extra honey is not available.
