I grafted cells for some 5 frame nucs on April 5. One of my nucs swarmed today. It was on day 28 of its cycle. I caught it and put it in another nuc box.
I found the nuc box it swarmed from. There were very few bees left in it, lots of pollen and honey. Missing were any eggs, larvae
or sealed brood except two sealed queen cells! My question is how and why did they swarm?? And if you are suppose to stay out of the
nucs until day 34 (per queen rearing calendar) how do you keep the nuc from filling up the box with pollen and honey and then swarming??
