It is still unclear how the virus was transported from the egg farm to
the
Banhams chicken farm, where it killed some 400 chickens and triggered a
drop
in egg production by other birds
400 chickens out of 35,000. Stick it in your calculator. Just
assuming a drop in egg numbers in one day of some 30 dozen eggs or so
is not call for screaming about some G.D. Flu Pandemic.
Some idiots taking care of the chickens could have caused such an egg
drop.....on purpose.

* Only viruses of the H5 and H7 subtypes are known to cause the
highly pathogenic form of the disease. However, not all viruses
of the H5 and H7 subtypes are highly pathogenic and not all will
cause severe disease in poultry.
* On present understanding, H5 and H7 viruses are introduced to
poultry flocks in their low pathogenic form. When allowed to
circulate in poultry populations, the viruses can mutate, usually
within a few months, into the highly pathogenic form. This is why
the presence of an H5 or H7 virus in poultry is always cause for
concern, even when the initial signs of infection are mild.
