Thanks for the input on the brood space. I tried putting the added super on the bottom and switching 2 frames of brood down to it . This seemed to work the best. I put one on top and did the 2 frame switch and they didn't go up as good as they went down. The 2 hives I did that on had almost filled up their super with more brood. I switched that one to the bottom. I extracted a couple supers of honey. Can I use this in the brood or do they like to make the brood cells different?
