this?

I mostly use single deep brood chambers(9 frames) which are often wall  
to wall brood.  In these hives I find the first honey super above the  
queen excluder is travel stained with the bees storing nectar and  
pollen then retrieving it for brood food.

I have had a hive for several years with 2 deeps as a brood chamber.   
They pack the brood boxes and take very little through the queen  
excluder.  I believe this is a queen issue as I have seen very few  
hives, over the years, refusing to pass through the excluder.
