Re: reverseing hives ?
Because I don't mess with the brood nest much I like to remove the bottom empty box and clean it up. I will already have an empty box to place on top of the brood when I remove the bottom box. Then it is a case of waiting for the flow before I put on the third box which is the bottom box that was cleaned up. It helps to have your boxes all the same size. I have observed that the bottom box is mostly filled with old pollen which the bees will clean out fast after the hive has expanded a bit.
