I have several brood frames moved up into supers to hatch/cycle them out. The following frame had a section of undrawn comb in the centre which has been drawn with new comb… thought it was worth sharing
I cracked open a few of my hives and the girls’ have nibbled away at the tops of the old filthy comb. They must have decided it was too filthy and had to go. I will report in a few weeks on what happened.
