Thanks for all your input. Here's an update. It appears that we will have to re-unite the colony, although we haven't done so yet. (were away for 10 days) We determined 2 weeks ago that the queen that swarmed is laying and we started feeding. However checked again today and there is no evidence of a queen laying in the abandoned colony, but there are plenty of bees and they are capping honey and there is lots of pollen. We treated with formic about 2 weeks after the swarm occurred. We also started feeding the abandoned colony. We will attempt to recombine, probably this weekend.
Here's some more questions: The top deep hive body of the abandoned hive is getting quite heavy with capped honey. The bottom deep less so. There is no larvae or capped brood in either deep. Should I put the heavier deep above the laying queen or keep the order the same? I assume I put both the abandoned deeps on the new colony (above the newspaper), but at some point should I try to get the hive back to 2 deeps for the winter? If so, how best to accomplish that?
