This experience might help others.
I picked up two packages of Carnolians on 4/12. I installed that day and noticed one queen was getting very little attention from the workers while the other queen was being lavished on by the workers in her package. Four days later I released the popular queen and got the response I expected from her package of workers. I released the not so popular queen. The response was "ho-hum". She slowly walked out of the cage, looked around, and then walked down between the frames by herself.
I waited a week before opening the hive to give everybody time to get to know each other. When I peaked in ho hum queen was laying. I checked in again today to find larvae that was about 3 days old, capped brood, queen cups, and one emergency queen cell that was capped, and no queen. So she probably kicked the bucket on 4/22 or 4/24.
Well, bummer!
I called my supplier and he had more queens. We were talking and I mentioned the questionable queen and what I found. I was prepared to pay, but he replaced the dud at no charge.
Sometimes duds just happen.
I scraped out the queen cell and put the new queen cage between frames. Rear ends shot into the air, wings fluttering and happy bees.
