Thank you, Angela - indeed, dark yellow to orange/brown cells in upper central area are partially filled with fresh honey.
But this piece of honeycomb was an example of originally made (from the beginning) by bees. Apiarists prefer rather regular forms (rectangles with constant thickness) - so they simply remove such "constructions" from hive.
Instead they put inside comb foundations (thin layer with cells pattern, reinforced with 4-5 thin (0.4 mm = 0.015 in) steel wires and spread on wooden frame) - and bees rebuild full honeycomb.
Unused honeycombs are the source of wax (needed to cleanse from garbages by filtering melting wax).
We have little surplus (a few dozen litres) above "must give" for family and near neighbours
For the highlight I may quote typical price for 1 liter (~1.4 kilo) honey in Poland: 12-16 USD (sold directly by apiarists).
Anyway, it's PURE hobby for us - we really don't care whether it is profitable business, or not. Simply enjoy seeing healthy and vital bees.
Surely, there is potential in our apiary to get much more honey (and money). If someone explores more these Littles...
