Re: Swarm cells and emergency cells with only drone brood
I have read that as soon as the swarm cells are capped the hive already swarmed. So probably not a swarming situation but an emergency requeening situation. On the other hand, this hive could be swarmed already without a queen now. And probably half of the hive population remains. To ensure the survival of the original hive there should be many frames of the cap worker broods. A situation like this I would say it is queen less either from the swarming or a dead queen. We don't really know until you do a hive check. Leave some cells in the original hive for them to make a new queen if indeed the old queen is dead or already swarmed. Or if you can find the old queen then make a small nuc. Either way this hive will be divided.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
