Re: My journey towards treatment free
if you currently have surplus deep frames of drawn comb and honey you can go ahead and checkerboard a second deep over your singles, perhaps something like this, where e = empty comb and h = honey:
e e e h e h e h e e (southernly facing side to the right)
i'll be doing this with a few hives soon, a couple of which will become my cloake board hives for queen rearing.
after queenrearing, these cloake board hives will have splits removed from them to make up more nucs and to get them back to a single deep.
for your double deeps, consider moving the brood to the bottom and checkerboarding the upper as shown above, unless the brood nest is straddling the gap.
