congratulations to your first hive!
First thing to know - if they build comb like yours - they have a queen. So no worries there!
Next thing to know - bees don't build comb along the compass - they don't even necessarily build in straight lines either. So no instruction missed.
Yet, if you are in the northern hemisphere and have temperate to cool temperate climate, an entrance south'ish might be preferable, because bees like a warm sun bath. Give the bees a nice warm micro climate with wind protection, but no burning heat from direct sun. Next to a hedge, below a deciduous tree, on the edge to the wood would all be perfect.
Bees tend to follow an already existing start of comb. Thats probably the reason, why 'fake' comb works so properly. A line of bees wax on your top strips might coax them into following the straight line. If this is not
enough, for your bees, you can go back to your langstroth frames, remove just the (plastics) foundation and replace this with an inch of bees wax foundation at the top of the frame. You
should end up with naturally drawn comb with perfectly movable frames (if you need them). If you don't bother, you can of
course keep the comb 'the wrong way', especially in the brood box. Have a look at the 'perone hive' and how perone handles 'the bees part' and the 'bee keepers part'. Perhaps you just give your bees a second langstroth box to fill with comb the way they like for the 'bees part' and give them a little more guidance in the 'bee keepers part' what in a langstroth hive would be called 'supers'.
what do you think?
