And here's the hard to reconcile thing: if everybody did their absolute best effort, investing 5 hours a week in the family or local cooperative chicken farm to get their eggs, and nobody bought mass produced eggs anymore, salmonella and other disease deaths would skyrocket. Not that everybody who raises chickens for the eggs gets salmonella, just that modern rates are so low - a return to individual farming would see them rise 10x, maybe 100x - even with conscientious chicken ranchers.

Now, get real about how much effort most people would actually put in on personal chicken-egg operations if they had no mass produced options and you're looking at 1000x increases...
