How long is a piece of string. Depends on the weather and the availability of drones. What’s the forecast and do you still have drones? Some of my colonies have started throwing them out.
Yep inspected some today and drone brood still being reared, main reason today was a stores check which was low in the BB's.
Meanwhile in the garden I have a ss hive and a nuc both with sister queens ready for mating, a quick look in the nuc and the nice marked QC is open as expected.
