Great comments. Thanks to all for the education on this. To one not too familiar with this industry I would think that an investment in systems / procedures to minimize flu infection might offset the financial burden associated with the destruction of the infected flocks; although the course of action taken does not support this thesis.
I'm no rocket scientist when it comes to hens / eggs, but might there be a hen or two out there in the infected flocks that possess a gene that is resistant to infection by this strain? If so, destroying the entire infected flock eliminates the possibility to discover which hens survive. Just wondering. Comments?
