Reply to comment by JennaSais in Why do poultry producers kill their stock when they get bird flu, rather than keeping survivors to reproduce? by poorbill

I think you might be half missing the point - the conditions are practically the best case scenario for engendering the creation of extraordinarily virulent diseases, and with such a huge population to infect nearby, high lethality doesn’t have the reproductive evolutionary disadvantages it normally does where the host needs to survive long enough to transmit.

No, I get that, but I'm saying that unfortunately for this one that horse has already left the barn, so to speak, so if the system changed tomorrow it would be just as bad as far as this virus is concerned. The same mortality rate would apply to those newly-freed chickens. And since it infects other species of fowl (ducks, for example) with less lethality it actually has all the advantages of a lower mortality rate while still being able to infect and be more lethal to chickens, whatever their living situation.

I absolutely believe we need to stop keeping animals of all kinds in conditions like that, to be clear, for this and many other reasons. That's why I got chickens of my own.
