I am considering splitting my only TBH this spring, I do not believe I want a second TBH at this time so I am thinking about doing a shook swarm type of split into a lang (frame med) before they swarm. I have plenty of resources for lang style hives so I figure this would be a good plan. Oh yeah I am also going to experiment with foundationless in one lang this year so this would be the one. I figure I could place a frame or two of brood from an existing lang and a frame or two of pollen and honey and the rest empty frames. I was wondering if the brood frames from the donor lang should contain the nurse bees or should i remove them. Also when I brush the TBH into the split how many bars of bees would be sufficient? I figure there should be 10 to 12 frames of brood in another week (very large bars but that is another story)
