Re: Going small cell
Well if you are using plastic comb it should be simple enough. But if you are using wax foundation, initially, the bees will draw it very poorly, in the process of drawing it they will enlarge the cells. So with a 5 frame nuc, me anyway, I would start by putting one frame of small cell foundation right in the middle of the brood. The hope is, that as the bees start drawing it, the queen will lay eggs in it immediately, before the bees have time to enlarge all the cells. Once that's done, feed in another frame of small cell. Continue this, and start removing the large cell frames. Once you've got some small cell bees hatching, they'll start doing a better job of drawing the small cells. But you'll likely have to cut the comb out of the first combs they draw and put new foundation in, once the bees are drawing the foundation better.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
