Not really. Especifically in the case of the bird flu, that was mentioned above, chicken get them from birds in the wild. So commercial poultry sometimes might have its advantages.
I take all of that with a grain of salt and concentrate on providing the best farm environment possible and allowing nature to mitigate the issues for me. This is way it was done for millenia before corporate agriculture and media got involved. Non-mainstream education is paramount in this area.
