Yes, Susan, I found this to be the case with the half dozen New World
Carniolans I tried. I gave them two deeps, and they made a nice
honey-barrier above the brood, and no "towering" brood nest resulted.
Unfortunately, they were the worst hit by varroa of all the colonies as
well. (began buildup of second year well, great wintering, but began dying
off in droves with lots of deformed bees, before end of May. The local
mongrels kept on building up, tho I found Varroa in them too.) Any idea
why?
