Cao, you totally called it. I am so glad you said something.
I inspected today and found drones in 2 hives, tons of drone comb in another hive. No queen cells yet.
The hive with nothing but drone comb seems to be queenless, so I borrowed a frame of brood from another hive and a frame of eggs from a 3rd. I left them at one box.
Fed everyone syrup and put supers on the hives with queens.
Here's to a year of lots of honey.
