I opened the nuc today to add another frame of brood/eggs - I actually found one on another hive where I SAW the eggs - didn't just guess since there was tiny larvae. This frame had lots of new eggs. It came from my crazy comb hive so I hope the new queen, should she come from this frame, won't have crazy-comb genes.
Anyway, I opened the nuc and it was calm - no roar so maybe the queen did emerge. I took out an old frame to add my insurance egg/brood frame and it was crawling with wax moth worms. I scraped them out with my hive tool and squashed them and pitched them off of the deck. The good news is that the frame wasn't being used - there may be some pollen in there, but it was at the edge of the nuc and they weren't really using it. I so no more evidence (just from looking down into the nuc) of any other wax moth stuff so I put the new frame in next to the two other brood frames.
I also wanted to continue to feed this little nuc, but we are in the middle of a drought and I didn't want to use my Boardman feeder any more since it promoted robbing from other hives. I put 1:1 sugar water in a baggie and laid it on the top of the nuc frames and snipped an X hole in the top of it. Before putting the nuc top back on, I put the bottom bars from two frames on the long sides of the nuc to hold the top up high enough not to smash the baggie. Then I put the top back on.
I hope the queen is there and if not, I've given them yet more resources to make one. Weak hives do have struggles, though - wax moth, and I see SHB in the nuc as well...and it's hard for them to defend when being robbed.
