Hi All
> My bees sometimes build comb above the top bars of the frames (Between the
frames and > the inner lid.)
The bees may well be crowded, but you should measure the space between the
top surface of your frame topbars and the under surface of your inner lid.
This space should not be less than 6 mm or more than 9 mm.
