US chicken companies pioneered restricting sleep to keep birds eating around the clock.
A new study (Li et al., 2026) recommends giving chickens just 2 hours of darkness nightly to maximize the time they spend eating. The study and photo are Chinese.
We know chickens have far better hapiness with 7–8 hours of darkness to sleep.
But they eat more and grow faster when they are sleep deprived.
Completely unrelated to food or animals, I personally also know this from the tech industry. Instead of giving away old devices to schools or for universities, you rather shredder them because support may be expensive, it may canibalize the sale of newer devices, etc. Millions of dollars just made to e-waste because the system is sick. I am sure every industry has these stories.
