I have seen drone foundation that bees have engineered to worker size.  I
tend to agree with Dave that we should let the bees guide us as to what is
best for them so we can assist, not work against them.

On the subject of drones, does anybody know whick part of the body of the
developing drone is attacked by the varroa mites as a feeding station?  I am
prompted to ask this because today I noticed a number of drones in a colony
each with a bald spot in the same place on the thorax.
