I bought two 4-frame nucs from a local gentleman and put them in two 10-frame deeps about a week ago. I feed each of them 1:1 sugar water from a boardman. There is a decent sized citrus grove right here, and there seems to be a strong nectar flow.
I noticed that one of them ("hive B") had much less outside activity, but was consuming the sugar water about twice as fast as hive A. I opened both of them yesterday and found almost no capped brood in B, and some queen cells high on the frames (abt. 3-4). I found the queen; she appeared healthy.
In the remaining 6 frames, I had bare duragilt foundation. I noticed that they had done a decent amount of comb drawing on 2 or 3 of their new frames, and were also making a bit of burr comb. Then, after doing some work on their hive yesterday, I noticed that they drastically ramped up their outside activity, with levels comparable to hive A. They are still consuming the sugar water about twice as fast as A also.
What's going on with this hive? Are they about to supersede? Swarm? Should I do anything?
