One week ago I pulled 2 frames of drawn comb out of the top brood
chamber of a 2 chamber hive, and replaced with empty frames with 1/2
in strips of foundation at the top.
Today I checked the bees,and they are drawing three "tongues" of comb
inside each frame; not filling the space yet but progressing.
Question- how do i transition the hive over to these open frames
without foundation, without causing major disruption to brood
rearing? and is it a good idea to use standard langstroth hives for
this TBH practice?
