So I keep stacking and she keeps laying in them. All 8 frame meds I am up to five high on one. They will lay up the four in the middle then move up leaving the outside frames empty. A few are doing this not just one. Funny story, friday I had to move a few hives out of my yard so I could spray roundup and shoot some cardinals. The tall stack was so top heavy it flipped on its side when I hit a few bumps two of the boxes rotated just enough to expose a small opening. In a cloud of bees I had to retrieve my suit which was in the back of the truck, the rest is history. I re arranged one yesterday and added a Q.E. for experimental purposes only. Not sure why they are not constructing this so called honey barrier? Any suggestions?
