Had a setback due to impatience. Live and learn I guess. I put one of the hives back together too early and they went right back to building queen cells so I just split them again. I thought it also odd that the parent hive with the queen had not torn down the queen cells after 7 days. Despite not being able to find the queen (there are fresh eggs), I merged them anyway. So I moved the queen hive again except this time I did a much better job getting all nurse bees out/off of the AS including the flow hive. I also removed the queen excluder since there is now queen. So the 10 days starts again.
The other hive is going more like text book, though I need to get into them and remerge them since tomorrow is day 11. I did peek in the other day and confirmed the parent hive had torn down all queen cells.
