What constitutes the time to rotate the brood boxes in the spring? Clearly it has to be timed just right. To help prevent swarming, but not disrupt the cluster too early. Does one wait until after the last frost? Do the days have to average out to be above 55 degrees, nights above 40 degrees?

when all the brood is in the top box, and the bottom is essentially empty, switching boxes gives the bees empty space above the brood nest that they try to fill. good luck,mike
