I got a question the other day that is re-occuring and wanted to answer it here.
“I’ve got this cross combed Lang that I want to move to a top bar hive since I have to cut into it anyway” – Anon. fan
First, Pick your battles. Transferring an established lang to a Top Bar Hive is a silly battle 95% of the time.
If your goal is to :
1. De-cross comb it, then take the bottom crossed deep. Put down a cloth on the ground, flip the deep upside down, Push all the frames out in one lump, then easily seperate all the frames and put them back into the deep fixed.
2. Starting a new TBH, then go thru process 1, but find the queen. Put her in the TBH, Shake in 3 frames of bees. Cut a single comb out with eggs in it (to anchor them from absconding) attach this to a bar with string. Finally swap hive places with the lang, so the TBH gets all the field bees. The lang will recover and re-queen while the new TBH nuc will immediately build out comb and start re-brooding instantly.
