I went with the advice. Ironically, the nicest frame to give them was the one I took out of the Nuc a few days ago. It was one that I had notched, so it had several uncapped queen cells on it, which I had to destroy. Since there are a couple of capped Queen cells in the parent hive I figured these younger cells were dead no matter what. I did take the extra step of misting the bees with sugar water. It's been a super interesting few days for me, experimenting with the OTS. Sure I had bumps along the way, but it's been fun and educational.
From my strongest hive I now have two Nucs (one with the old queen and one raising their own). From my second strongest hive I pulled a Nuc and sold it to a friend and they are now raising a new queen. My weakest hive I left alone, but in a two weeks It will be strong enough to give me another Nuc. Since that weakest hive was not very productive I will re-queen it with a purchased queen and hope for an improvement. I can see how making new colonies can be a bit addictive. It's certainly easier than extracting honey for sale.
