If the bees have been in transit several days before I install, them, they are well on the way to accepting the smell of the new queen. I take a sharp nail and make a hole thru the center of the candy after immediately removing the cork. After three days I go back in and if the bees are trying to feed and care for the queen thru the wire, I release her after pulling three outside frames and sticking my hands and the cage down to the bottom of the hive body. That way she runs under the frames instead of possibly flying away.
