I had a 2 hives that were either all mediums or only had 1 deep the rest mediums at the start of spring. I added an empty deep with plastic foundation on the bottom and placed the rest over top. Over the summer, they did some work on the lower level. but when I checked them recently they have completely abandoned them. I understand it is too late this year to do anything with them and plan on pulling them when I put on mouse guards. I also had another one that was a NUC that they have completely abandoned the 5 frames in the bottom that came with the NUC, I am assuming because they are so dark and old, but they also abandoned the outer ones about half drawn out. What can I do different next year to get them to move into the Deeps?
