OK, here is the scenario. I have six hives all with one deep and a medium right now. All have come through the winter with a little feeding over the last couple of weeks. Here is what i need advise on. I checked all of the hives this past weekend and all had a significant amount of brood in them so i know that they will start to explode shortly. I didn't see any queen cells as of yet so hopefully none will swarm right away. Here is my question. Should I go ahead and add another super now or wait? I have supers, but all of them will have new foundation. The flow is not on yet although the bees are gathering in some pollen already i noticed. Should i add the next supers and feed so the bees can build the new foundations out and then add honey supers later or should i just wait and add the honey supers later when the flow is about to start? Keep in mind that regardless of what i do, any supers that get added from this point will be on new foundation. Thanks in advance for any advise anyone can give me.
