Re: Dead virgins in JZBZ cages
I use the JZBZ cages to hold my newly emerged queens. They emerge into roller cages in the incubator and are transferred when I find them out of their cells. First thing I do is fill the tube with fondant and give them a drop of water. They are usually head first in the fondant whenever I check on them. MB is dead on the money with his advice, your new queens simply starved. A newly emerged queen needs to feed herself for the first day or two. After that, she will start to smell more like a queen and the bees will begin to feed her royal jelly. Keep your existing setup but prep the bottom of the cage, where the removable qe bar is, with a bit of fondant first.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
