Re: Early reversal - rolling the dice
Quite a few of my hives have their brood in the bottom box since the top box is still full of capped stores. The bees should have stayed with the brood and all will be fine. That said, is is early to be rotating boxes for me in zone 7a. I just do not like rearranging the configuration until the temps stabilize a bit. Maybe in another two weeks as the top boxes fill up with brood in the other hives. With the nucs I am making, I can control the amount of both bees and brood to some degree so there is less of a concern. I over wintered several nucs containing just three frames of bees in a single deep 5 frame on screened bottom boards with the plastic insert.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
