Question for experienced beekeepers: Do nurse bees move eggs from one cell to another?
I’m not new to beekeeping but I've read conflicting information over the years. One view is that nurse bees can strategically move eggs to create new queens when needed. The other that this is simply a myth, and that nurse bees cannot move eggs because the queen glues each egg firmly into the bottom of the cell when she lays it. I've leaned towards the second explanation, but something I've recently observed has me questioning that.
Here's what happened:
13 June (Day 0)
I made a makeshift queen enclosure by cutting up a plastic queen excluder and attaching it over a small box. I placed the queen inside the enclosure and returned it to the hive on an empty frame with just a strip of foundation and plenty of empty space. I’m doing this intentionally to make a forced brood break as we don’t get a natural brood break here in Sydney, Australia. Photo 1 shows the enclosure when I was assembling it.
20 June (Day 7)
I inspected the hive a week later. There were no eggs or young larvae anywhere in the brood frames, so I felt confident the queen was securely confined. The colony was calm, suggesting she was still alive. The bees had started drawing fresh comb around the enclosure frame. There was still plenty of capped brood and some older uncapped larvae, exactly as expected.
27 June (Day 14)
This is where it gets interesting.
On the newly drawn comb surrounding the queen enclosure, I found several charged queen cells. Inside them were young larvae that I'd estimate were about 4 days old. There were no eggs in any regular worker cells anywhere in the hive, suggesting this isn’t due to the presence of laying workers and it’s too early for that. Photos 2 to 4 are from Day 14.
I know that nurse bees are capable of removing eggs from cells, for example, when a young queen lays multiple eggs in one cell or laying workers that lay multiple eggs in a cell.
I plan to let these queen cells hatch because I'm interested to see whether they produce queens from fertilised eggs or drones which could be from laying workers.
I'd appreciate hearing from experienced beekeepers who have direct knowledge or evidence either way. Could the nurse bees have strategically moved fertilised eggs from inside the queen enclosure to queen cups outside the enclosure? Or is there another explanation for what I'm seeing?
