Whether its conspiratorial or not, what concerns me is putting all of our eggs into one basket so to speak. Having so much of the nations poultry supply concentrated into these locations, where a big viral outbreak can so easily take it all out seems crazy. A few years ago when the African swine flu broke out in China and killed over 1/3 of their breeding stock, I had to wonder also if there were any bad actors at play.
Even if there were no bad actors in these instances, who is to say there won't be in the future? Backyard flocks, and guys keeping a few cows and pigs might not be the most economical way to produce food, but at least there will be a chicken left somewhere (hopefully) if things got really bad. I would also throw meat packers into this category. There used to be a lot more small packers around (or so i hear) and during covid we saw that if two employees at a plant get sick that could mean 5,000+ head that don't get processed that day.
I'm not trying to dog on how anyone makes a living either, I feel for the farmers in these cases.
