I don't understand why if a chicken farm gets bird flu, they have to kill them all. What about culling the dead ones, and the ones who live through it are now immune or more resistant to the bird flu? Why can't they take the infected chickens, kill and cook them and package them for consumption, like chicken fingers or nuggets, or even bbq chicken, frozen and packaged? Cooking them kills the bird flu, as long as you don't have sick workers.
Too many big farms, and big chicken houses, and even big ranches. Smaller and spread out you have less sickness spread and less impact on consumers.
Smaller farms and farmers like before WWII made for a saner system of food production. Before WWII 45% of Americans lived on farms. Small farms went out of business during WWII so more men were available for military service. Larger farms took over or bought out the smaller farmers.
I wish I lived out in the country on some small acreage. I would raise chickens, rabbits, and have a big garden. Hunt and fish when I could. 2-3 acres could feed a family. Also have some fruit and nut trees. My grandparents had 10 acres. They had gardens, raised chickens, had pear, apple, peach, plum, and pecan trees. They gathered wild blackberries and muscadines when in season. Always had plenty of food. They hunted and fished also.
