Out of curiosity, I'm interested in tracking the changes in hive
population, and so I was wondering, is there any way to roughly estimate
the number of bees in a hive ? I considered:
 
* weighing the hive, but of course that includes all the honey etc, and
I'd probably need a small crane to lift it anyway !
* tipping all the bees out into an empty box, and weighing that, but that
seems a rather an unfair disturbance on the poor old bees (particularly
the queen).
 
Any ideas, perhaps it's possible to estimate the no. of bees based on no.
of frames covered ?
 
Thanks
