I am getting ready in a few weeks to try the punch cell method for raising some queens. I have decided on the wide base JZBZ cups over the Nicot mostly for a cost factor. My ultimate goal is to overwinter Nucs with another batch of queens from this summer. I am nervous about my timing calculations. Is there a cage I can slip over a finished queen cell in a JZBZ cup, in case my calculations are messed up? I hate to go through all that work and find only one queen that killed off the others. My first couple of times I would like to protect the queen cells and make sure I completely understand the correct size larvae to use and have a solid understanding of when to pull queens out. Thanks for any help!
