My strongest hive became queenless about a week and a half ago, and I placed eggs and larva in there for them to make a new queen. But surprisingly, they didn't make a new queen out of them. A few days ago I placed a swarm cell in there from another hive. They didn't seem to do much with it and it isn't capped completely yet. Today I placed more in there and they weren't completely capped either. Will they do something with these? Why didn't the make one from scratch when I gave them eggs? If they don't do anything with these cells, I plan on ordering a new queen. Thanks.
