His idea is eugenics but for chickens. Just let it spread it through all the birds and the ones that get infected will die and the ones that are immune will survive and breed and the chicken race will be stronger for it.
Yes the idea is that birds that recover from bird flu will keep producing. You end up with more live birds than culling entire flocks. Some of the birds survive, because of their genetics.
Too bad about the human race though, I guess.

So... animal husbandry?
