I remember reading on the Bee-L a while ago some questions and answers
regarding how many drone laying colonies to expect, etc.  I think it was
Vince Coppola who said that this was becoming (or is) a major problem.  I
just went thru my 140 colonies in eastern PA and found 7 drone layers. This
is far more of this kind of thing that I can remember.  These bees were
recently inspected and found to have few or no varroa mites (most yards had
no mites in several ether rolls and a few had one mite in several ether
rolls) and no tracheal mites.
 
As I believe Vince asked, may we have some futher discussion on this, or
comparison of others' observations?
