It's too late now, but I have had two hives that swarmed. Both hives had at least 15 queen cells. Both queens left 4-5 frames covered on both sides with 90% coverage in brood. I didn't think I could control these hives from swarming. With this number of queen cells I didn't think even splits would help. Here comes the confusing part, both hives are queenless now. Both hives have a strong bee population but no brood and I can't find a queen in either of the hives. I have ordered new queens and will put them in as soon as they come in. I guess that a hive can be strong enough to put too many swarms together and all the queens will leave. Any one with similar experiences? Richard L. Barnes [log in to unmask]
