when my menthor gave me a swarm i wasn't sure about what to do...i mean, he just said put it in a hive with this already built frame that he gave me and feed it a little. so i did. but the next day, bees were still like the day before, in a form of a cluster left of the already built comb, so i had to poke them just to see if they'll finyll move. khm...that wasn't a cluster, they built a comb in size of one frame completely straight, aligned with the frame inside, over night. then i put in 9 empty frames, i think they drew them...maybe a bit more than a week, swarms are mad about building combs.
but like some said before, if there is flow, they'le build.
which gets me thinking...would they build comb in autumn when we are winter feeding them? the feeding is supposed to represent a flow-it does stimulate the queen a bit, doesn't it?
