Re: Adding queen cell to an existing hive?
When are the cells due to emerge? You might be able to figure out where the queen is before that happens. Right now you have a lot less bees in each nuc, maybe go through them again? Ultimately one queen will prevail if the old queen got put in a nuc with a capped cell. My guess is that it will be the virgin queen. I am a pro at moving the queen inadvertantly into a nuc that is supposed to be a walk away split so I know where you are coming from.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
