Opened my hive today to find that:
Yes, the bees consumed (and were still actively consuming) the dry sugar I applied 'mountain camp' style last month - they used about 3 lbs. I would estimate, with a little loss to falling through the frames.
No, they did not seem interested in the pollen patty that I gave them over the last two weeks. They are bringing in a good quantity of pollen now, so I guess will be even less interested now.
BTW, can I save the left-over pollen patty in the freezer for next year, or will it be shot by then?
