Re: Feed Sugar on the inner cover
This only works in warmer climates. Bees stay in a tight cluster when hive temp is below 55F and the cluster only moves when hive temp is 40 to 45F.
Had a hive dive last winter in February in cold weather. It was a late swarm capture and I knew it was light on stores. Had 20 lbs of sugar above an inner cover with an open 3 1/2 inch round hole in the center and the cluster got stranded in the frames.
Far better to have emergency food on top of the frames.
If you always do what you always did, you'll always get what you always got!
