I beleive an upper entrance can be important during a honey flow.  For upper
entrances I use auger holes in my honey supers.  I use shims for other
various management purposes all during the year, but have never used them
between honey supers during a flow.  This is my question for the list.  Are
shims used this way a violation of bee space and wouldn't this space be
filled with burr comb during a flow?
