Just installed 2 packages on Mon. 4/9 since then neither hive has really worked on the syrup very hard. One has a top feeder on it and the other has a entrance feeder, syrup has been mixed 1 to 1. 3 days later and I still have a half a quart or so left on each hive. I don't know but we did have a cold spell come in since Mon. maybe that has slowed them down. Anyone with some input?
