I've been trying to feed my "at home" hive for the last week or so. So far they have refused to take any of the syrup. The first batch I mixed 2:1 and added a ocuple of spoons of honey for flavor. They didn't take any of it. So I dumped it out and tried straight 2:1 this morning. I just checked on them and the feeder is still completely full. The hive has about 70 lbs of honey and should make it through the winter, but I wanted them topped up to about 100. I know from my inspection a little while ago that they have at least 6 empty frames where the brood nest used to be. The hive is full of bees and some still fly to collect pollen, even though we have had a couple of frosts. I am using an inverted pickle jar on top of the inner cover. I am puzzled as to why they are not taking the feed. any ideas?
