"I looked for at least two hours to find a good explanation for this. I know 
that inbreeding
leads to low brood viability but I have never heard of 100% inviable eggs."



Thanks for the search Peter...I could not find much information on my google 
searches either and at this point, any explanation to this puzzle is a good 
explanation.  First time in 25 years I have seen anything like it and I hope 
to not see it again.  I was at another two yards yesterday and found 5 more 
colonies with the same problem.  I just spoke with a fellow beekeeper in my 
province and he seems to think that it is chemical related.  I am hesitant 
to jump on the chemical bandwagon.  I understand the concept of brood 
viability but these colonies were doing fine with brood rearing and managed 
to build up and bring in a honey crop.  It is as though an egg viability 
switch was turned off and the colonies petered (no pun intended) out.
