Last week I spotted multiple queen cells (QCs) in one hive and feeling energetic, cut several uncapped, charged cells out and secured them to an empty bar. I placed it in an empty box and placed that over a queen excluder (QE), over an active hive body. In two days they were capped, so on next Saturday, we should have a birthday. I plan either today or tomorrow to separate the cells and re-glue them to their own bar(s), then place each over a QE, over an active hive. That way, when they emerge, they will emerge into their own medium box and I can mark them before introducing them into a hive. Yeah, somewhat convoluted, but it is a process I understand.
