I returned to TO today to check on a trapout I setup on the 6th (so 10 days ago).
The Bees have moved in to the NUC box. The home owner put some plastic around the box to make it withstand the rain better.

When I opened the box up, the 3 frames that I put in were filled by the bees with uncapped honey. Sure sign there is a nice nectar flow going. I didn't see any brood/eggs. So I assume it's safe to say that the queen isn't out jet (the owner at certain times saw the bees come out 1 per second) we decided to leave the NUC box there for a few more weeks.
