I put a second deep on about 2.5 weeks ago and checked it yesterday. About 70-80% of the frames are covered in comb and bees, but 90% of the cells are empty. Reading some of the past forum questions and answers, I know "when do I add a super" is a common question with a pretty consistent answer (when ~80% of the frames are drawn out).
My question is this:
Should a super be added when ~80% of the frames are full of empty comb?
Should a super be added when ~80% of the frames are full of full comb (brood, pollen, honey, etc)?
Thanks in advance for the clarification!
