What to do?

[Wilco]

I've got a nuc which is giving me bother. I was rather hoping to have come out in hives but it's being awkward.

Situation:
Nuc from May with a 2021 Northumberland Honey Buckfast queen. She was accepted and they were doing OK (not growing as fast as the other NH colony but OK). Then last week they appeared to be superceding her. Went back to reduce QCs down but in so doing spotted what I believe is a bee with CBPV.

At this point do I:
1. Let them be(e).
2. Unite with another colony
3. Transfer them to something I can try the bottomless pit approach on even if it means they have a lot of dead space (about to go away and don't have dummying kit made up nor time to make any before going).
4. Decide as it's a small Q- nuc it's not worth the fuss or disease risk and seal them up tonight.

Aye I couldnt get it to load.
Funny you calling it a bottomless pit

I mace minimal experience and no expertise…..
I had a hive with possible CBVP .this year I essentially split the hive into 3 nucs and left for ragging bees in the original hive.

Strangely only 1 of those nucs seamed to have dead bees outside for a while (less than 2 weeks. ) however I must have put more capped brood in that one as it is now the strongest of the 3 it didn’t manage to raise a queen, so I have since introduced one. the weaker nuc did manage to raise a queen
The 3rd has the original queen, on new comb and seams to be recovering with no sign of cbpv

I would leav b and see what has happened on your return.

I have seen no issues with transfer of CBPV to colonies nearby (2 or 3 feet either side), so no need to seal up. I'd leave them to it. If they want to supercede, let them.
One bee with CBPV is not uncommon and not serious.
