Our NUC experiment was a failure; the Bee’s were not able to create a new Queen. I suspect because the brood we gave then was over a week old.
The hive does have some activity but there is no new brood in the hive, so the existing worker and flying bee will eventually die without a queen.
Opened up the hive today and discovered that all the food that we supplied to get them started has all been eaten now. So its days are numbered, very sad but we did learn something.
