Re: Did my attempt to checkerboard cause a swarm?
paul, thanks for sharing those results. i had similar experience with a few overwintered nucs that i was trying to add more boxes to. i also put empty supers in between the broodnest and the overhead honey, and they swarmed.
it's like they didn't like that empty space there, or didn't perceive that it was there for them to grow into.
i think that in the future, i will try to keep frames that they are working in each box so they can ladder up. and, i'll not put more than one empty frame at a time between those worked frames.
this is my second full season, and i'm started to get more of an inventory of drawn comb. i'm hoping that will help out when it comes time to checkerboard and expand the broodnest next year.
