This may sound like a silly question. A couple of friends have run several hundred hives for several years as 1 1/2s (Deep and Medium)with the deep on top to provide easier access to the frame feeder. This year they are switching back to putting the medium on top. They are convinced that the queen is very reluctant to go to the bottom medium. They say the bees won't use the bottom medium for anything at all and is totally wasted space. I do think that queens like the larger combs somewhat, but I don't understand why the configuration has not worked for them. I was considering shifting to this configuration, but now I am concerned that it won't work well. Have others had success running 1 1/2s with the deep on top?
