2 weeks ago we were invited to a requeening party. Two colonies had lost their queens and 2 new queens ( Buckfast strain) were delivered in their own private cages with a few nurses. A candy plug was attached at one end which they would chew through in a couple of days during which the colony would accept the new mated queen.
After a lively group consultation we proceeded to the hives and placed the caged queens, between two brood frames, centrally. and fed them sugar syrup. Let’s hope all is well now.
