Third year beekeeping, but first time making a nuc. Was trying to find the information I needed by scouring the internet, but I couldn't seem to find the answer.
I had purchased a queen to add to a split for my NUC. She was quickly killed within a few days as they didn't accept her, so I am allowing them to raise their own queen. It's a 5 frame NUC so I added 4 frames: fresh eggs, larva, capped bees, and a full frame of honey. This left the last frame blank. I had noticed a day before the queen died it looked like they were already drawing emergency queen cells on the egg frame, but I ignored it not have ever seeing those cells before. When I pulled the dead queen out I added an additional frame of eggs(replacing the empty frame), so they would draw those into queen cups instead of the older frame of eggs.
Now that you have the background, here lies my couple of questions. We inspected 5 days later and they had drawn emergency queen cups on the original frame of eggs(five of them). They were also starting to draw additional ones on the new frame of eggs added after. Since those eggs are staggered in laying times I assume the queens will hatch at different times. What will happen, and should I intervene in anyway? After reading about cast swarms, and anything else that can go wrong on larger hives I was concerned. That is the very basic question.
Secondly, there are a lot of bees in the NUC most never drifted back even though it's sitting about 4 ft from the original hive. The bees in the nuc are back filling with nectar, as a lot have turned foragers. Since I don't have a blank will this be a concern as well? I am getting into the timeframe in the next couple of days for the queens to hatch, so I wanted to leave the box alone until after mating flights/laying. However, I'm not sure what good it will do if she mates and comes back to a box with nothing but filled nectar and bees. I assume there has to be a tiny bit of room every day as bees hatch, but just uncertain of what to do.
Apologies for the lengthy post, and thanks for any help in advance.
