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 when they are sleep restricted.

Laws vary by state but iirc, California banned caging entirely, including imports. That said, cage free doesn't mean quality of life.

I notice a huge difference with the more expensive eggs cause real free roaming hens eat lots of bugs and produce better eggs with deep orange yolks. Though, naturally scammers ruin that cause some orange hued eggs are dyed so buyer beware.
