Did introduce queen fail?
I introduced a queen to a queen less hive after removing the 5 queen cells, through a queen cage. They climbed on the cage and came off easily when trying to push them away.
Fast forward 5 days, the fondant is gone and the cage is empty. I searched every frame in the brood box (not honey box since every frame is capped) and couldn’t find her anywhere. The bees where also more aggressive then normal. Should I be concerned? We’re they aggressive because of a new queen or because they’re queen less?
