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.
Where do you think the stuff the meat animals eat comes from? You think there’s not millions and millions of acres of land producing solely cow food right now? Do they go out and pick all the feed corn by hand so they don’t crush any little mouseys nearby? Do you think a cow might require more food than a human?
