Help with nuc please

[tbonekel]

I placed a frame of brood, eggs and bees in a queenless nuc on Jun 9th. I check last Saturday on the 14th and noticed that there was one queen cup with larvae but not capped. Today, I checked and saw that there was another queen cup not capped and one that was capped. That one may be the one that I saw last Saturday. Okay, now here is the big question. I saw young brood in this nuc, I mean tiny larvae, the kind you would use to graft, but I looked and looked and couldn't see any eggs at all. I looked all over that thing and didn't see a queen. What's your assessment? What would you do?

If you made this nuc on the 9th and it Was Queenless.....then all brood would have been capped by now. So you saw larva, there is a queen in that nuc.

Actually, I already had the nuc and it was quenless for some time. When I put that frame in on the 9th, they had nothing but pollen and nectar. That's what is so strange. One possibility I thought was that I accidentally put a queen in there on that frame. But the bees started working in making a new queen pretty quick.

I would say you put a queen in on that frame. Depending on the stages of what larvae you saw, could have been a virgin. But likely not. The bees that were there knowing they were queenless took the chance to try and make one as soon as it was presented. JMO

Now that there is evidence of a queen, either you pull her and allow the other cells to progress or cull them. She was just getting started in the new hive. If you want another then move her and some to another nuc. If not then they will take care of her or die trying.

If the nuc had been queenless for some time..  30 ish days give or take a few, it is possible laying workers were starting to kick in..   
   It is more likely that a queen got moved on the frame. As mentioned, the bees started Making one.. If the queen in there cranks up well they will likely tear the cells down when the brood pheromone is stronger..  Provided the queen cells do not emerge first. Provided the bees or the current queen do not kill the un emerged queens...  Provided it is actually a queen, and not laying workers...  Good GRIEF Charlie Brown! Isnt Beekeeping fun!

Oh the endless Provided's......

Better check the donor hive. It may be queenless or have a queen in the makings

along lazyBkpr line of thought it could also be that they raised a queen but she was not left long enough to mate and start laying.
Check doner colony as Riverrat said. Look for more than 1 egg in cell as Lasy said as so when the larva is caped ids it smooth like worker or bullet like drone?
Give it a few more days and all should become clear.
