I caught a swarm about a week ago - first one for me. I got about 80% of the bees. The folks whose yard it was in contacted me today saying that the remaining bees are still there and have started building comb.

Three questions:

Does this mean I didn't get the queen?

I'm going back tomorrow to get the remaining bees, will they merge with the bees I got earlier okay?

Is there any hope whatsoever for the swarm to survive the winter, even I feed them? (I'm in Vermont).
