I caught one of my own swarms last weekend. I placed one frame of capped brood from another hive to try and anchor them since I lost two swarms previously. So far this seems to be working. I checked this evening and they are filling 10 frames of a deep. I am feeding them on top of the inner cover. They are taking some, only 1/2 quart so far, but there are a lot of bees just hanging out in the empty space on top of the inner cover. The question is should I add another deep of undrawn foundation, or should I wait until they have drawn out 70% of the first deep?
