Tec and riverbee,
I bought 2 nucs this spring from a commercial keep in Fayetteville area. He has yards here, Florida, and I think Michigan (don't remember for sure) and I think he runs almonds in CA.
They were made in Florida from Harbo VSH Breeder Queens.
The nucs were crammed full of bees, more than covering all 5 frames. But one nuc was troubled from the start. It was queenless on arrival but had a capped emergency cell and lots of capped and open brood. I got back with Steve Aust, (my supplier) and he sent me a new queen priority mail. When I introduced her I found a little virgin queen and 5 more capped queen cells. I destroyed them and culled the little queen. They released the new queen themselves through the candy plug and she soon had an entire frame laid in near perfect pattern. Not long after that they turned up queenless again with queen cells built. She emerged and laid a half frame before she turned up missing. Again, another queen cell, the last one, which emerged and laid the frame I was referring to at the beginning of this thread.
In the meantime, the other hive continue to grow until it had drawn out 70 percent of two deeps. Then it turned up queenless and started to dwindle. So I combined the two, culling out frames full of SHB. That's the story of my ill fated journey with these bees.
