Need another quick advice if you may. Today I have caught a medium size swarm on my property, don't know where it came from, does not look like any of my hives. Anyway, I only had 5 frame nuc box on hand so I shook it in and they seemed OK with that (I put a couple of drawn frames in there, the rest is new foundation). I know that everyone says swarm may leave if they consider box too small, and I can put together full size box by tomorrow, so should I move them over right away or leave them in the nuc box until they outgrow it? The swarm was not large enough to fill full box outright, so they are not cramped or anything.
Which is less likely to result in absconding - staying in 5 frame nuc box for a week or two or being moved into another box just a day after being hived?
Thank you for advice as always!
