jen,
installing a queen in a fresh nuc that you want to add a caged queen..........and for everyone........
leave them queenless for at least 24 hours.
after 24 hours place the queen cage on top of the frames and watch the behavior of the bees. this is is a good indicator of whether or not she will be accepted. do not release her even if the bees seem okay with her. ( i never release queens out of a cage). put the cage in if you think reaction is relatively good. you can also leave the cork in for anothr 24 hours if you are unsure, then remove the cork to expose the queen candy.
if the bees react negatively when placing the cage on the tops of the frames, like you described jen, trying to sting through the cage, wait another 24 hours. try again. watch the reaction. queens can be okay in cages for a few days. just give a little swipe of water. jz beez cages are great because there is more queen candy in the cage (typically) than in the traditional benton cages.
what you want to see are bees peeking up at the tops of the frames, filtering up to the cage, covering the cage, touching her or touching with antennae through the cage, and fanning. if you see fanning at or around the cage, odds are she will be accepted. you don't want to see their abdomens or butts towards the cage, and you will clearly see this. if so, pull the cage, and wait another 24 hours.
