1 "Once the bees draw out about 15 "frames" [in a top-bar hive] , they seem
to idle somewhat. They don't seem willing to work too far back from an
entrance horizontally"
2 "Once they're up and running, you don't have to keep checking them to see
if
> they need a super.  Give 'em room, and let 'em go."

Statement 1 is consistent with other observations over the years - I have
used 21 frame hives for over 25 years. Unfortunately, it means Statement 2
is too simple - yes, left alone the bees go - over the hedge!  They consider
the nest 'complete' when it reaches 15 frames backwards from the entrance -
and swarm.  You do have to manipulate continuously, moving full frames to
the rear and bringing up empty frames - even then you have to artificially
divide the colony for swarm control.  It all becomes easier if the hive is
not too long - which is why I use 21 deep frames covered by one level of 20
super frames. Then it is much easier and less laborious to work than a
standard tiered hive. The shorter length also reduces problems of wild comb
building - combs get more 'free-form' the further they are from the brood.
