I installed a package 22 days ago on 8 frame medium foundationless frames and today I added another 8 frame foundationless medium box because the original has been drawn out on all 8 frames. But I added the new box below the original. Should I have put it on top? My thought was bees build down. But I just reread Beekeeping For Dummies and it says to add the new box on top. Should I go back now and do this or leave it alone? Remember my frames are foundationless. Thanks!
