My configuration is currently one deep and one medium. So I have not decided if I want to split to give me a third hive or just work on these two as to not swarm. However, by opening up the brood nest do you simply just remove a few frames and put in new frames not drawn out? Then what in the world do I do with frames of brood that I took out if I am not going to split? And you just pick, I think I read someone just pulling three out and dropping three back in, is this about right?
