"I took the supercedure cells and a frame of honey and placed them into a queen castle. then made a nuc out of some honey and a couple of frames of brood from the now queenless colony. I placed the Russian in her cage (cork still in) in the nuc for 4+ days and then uncorked her. 1.5 days later I took a look to find that they had released her and were in the process of balling her on the bottom board of the nuc"
keith, how long did you leave the nuc queenless, or did you place the russian queen in right away? just a comment, there really is no need to keep the cork in for four days when releasing a russian queen in a non-russian hive. typically, for non russian hives, not more than 24 hours, (overnight has worked), remove the cork, and check 4 days later. like apis said disturbance of the hive 1.5 days later, but not sure what happened.
