juzzer - If you ask any beekeeper a question you will get diff answers most of the time from each one. That's because there is more than one way to do most things with the bees. Some beeks like to do things their way and promote that way. So what I will tell you is this. Reversing the hive bodies early in the season will not do any harm. The bees had it set up last year the way they wanted it prior to winter. That was so they could find things through winter. This is a new year, the bees have already removed their resources from those bottom hive bodies so at this point there's nothing really there. Doing a reversal will only allow them to find the area again above them and start putting more resources into that area. Keep in mind you may have to do checkerboarding with your hives to get them to expand the brood nest, but hey that's beekeeping. lol.. Take my advice with a grain of sand as this is my method and it works fine for me
