I have 3 hives all started from packages in may. All 3 were building up really fast had really good brood patterns and were doing well. Up until the last week. I did my inspections left night and all 3 had very little 1-3 day eggs but a decent amount of capped and uncapped brood. I saw the queen in 2 of the hives but not one. In 2 of the hives I saw supercedure cells. One with a super cell in it I accidentally ripped out pulling a frame out so I pulled a frame of eggs from the hive that had the most to give them something more to work with. It seems to coincide with the drones coning out. Saw a few of them in the hives. Just seems weird that 2 would supercedure at the same time. Both only had one cell and I did see larvae in them as they were no capped. I would guess that the 3rd is going to do the same based on the amount of eggs I saw. I guess my question is for supercedure isn't there usually more than one cell built?
