Two of my hives seem to be struggling. They have plenty of bees, few drones, but they have not drawn out any comb on any of the brood supers since I put them there in April. The original four frames from the nucs are the only frames that are getting any action. They made honey above the excluder in pretty good quantities, but have put none in the brood supers. I am now treating them for mites and nosema and I'm feeding them like crazy with sugar water and honey bee healthy, but I wonder how to encourage them to spend the next couple of months getting ready for winter? What should I do? Thanks for any help, Joe
