I have two hives that made it through the winter and they both are looking good so far. I'd like to expand some this year but I'm confused as to whether I should split them routinely for this purpose. Obviously splitting reduces numbers/disrupts them for a time (depending on if you have a queen on hand) and I'm concerned about how much this will cut into the honey yield. So where is the breaking point between splitting 2 hives into 4 hives and just maintaining 2 hives (opening brood nests etc.) so they produce the strongest honey yield possible?
