At least so far the josephianae have been keeping their queen alive through the 28 degree spring nights. I opened up the Josephium and saw a shiny black queen with a few attendants in her cage surrounded by a cluster of defensive bees. I eventually managed to brush them off and pull out the cork. I put the cage with its candy plug back in the hive and closed up. I took out the caged and shook out the few remaining clingers and closed up the hive.
As for the Benedictium, I put in four more pounds of sugar dissolved into 2:1 syrup in the feeder pail.
