I had my hive checked for AFB today. It seems as if the original queen had gone some time ago as there is little brood, but lots of drones. There is also a young queen (we think), picture attached. What options do I have? Jeremy Macy who did the inspection suggested either a new queen, or a new queen and a frame of brood, or a whole new nuc. He also suggested I ask on here. All advice appreciated.
