New beek with 4 hives consisting of 2 deeps, started from 5 frame nucs. When the flow stopped, we began feeding 1-1 sugar syrup. They are going thru 1-2 gallons per hive every 2 days. I have a inner feeder on top of the deeps to try to cut down on robbing. If I have to continue to feed thru the remainder of summer this is going to get very expensive buying sugar. Do you buy sugar wholesale somewhere? Just let them fend for themselves? All suggestions are welcome.
