Had something similar with 3 hives. Haven't looked in 2 for at least 2 weeks due to weather. Saw queens in both hives, no QC's, no eggs or larve, some capped brood, polished cells everywhere in one hive. In the other hive some capped brood, no larve and some eggs on one side of a frame, again polished cells. The third hive hasn't been looked in for 3 weeks due to location (on a roof) and weather, no eggs, larve, some capped brood, polished cells, no signs of any QC's. This was last week, will have a quick look when I feed them again this weekend. Shoot normally does the roof colony off the back of his truck, but due to a cricket injury 5 weeks ago. Turns out he has done his acrutiates which will require surgery and has also broken his leg.....only 5 weeks to discover that. I'm having to scale a ladder as I'm a short arse to deal with them......not good with ladders.
