Looked into my nucs today, its been a week since I switched upper boxes and I wanted to see if there was any changes. The heavy box I thought I could harvest some honey but it seems there is new brood in the upper chamber so I left it for later. Lots of honey tho, just on the upper parts of the frames. The second box, which I suspected of being queen-less, still had some old unhatched brood in the upper chamber. Checked the lower chamber and to my surprise, there was newly capped brood. I must have brought the queen from the previous switch. That hive is fixed, now to watch the other. Did not look for a queen cell in hive No1 so will monitor, although both hives bringing in pollen, a good sign.
