I took a look at the hives today; it was 50 degrees, just a bit too cold for much activity. The Ambrosium and the Josephium had emptied their feed buckets, which surprised me, so I refilled them with 4 lbs of sugar each: 2 x $2.19. In the coming week, the temperatures should get up to 60.
I have seen little activity over the last month from the Benedictium, so I've been worried about it. When I looked in the attic, it was abuzz with activity, but they had not taken any of their feed. So I removed their attic with its feeding pail and reduced the hive to two deeps.
