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.



I don’t understand your point. It makes no sense. What do you want exactly? You want to keep them in farms but not eat them? Or keep them in farms and still eat them? Your argument is incomprehensible. There is no such thing as overnight veganism. And as we move towards a vegan society, animal numbers will normalize and become natural again. That’s just a fact.
I have no problem with eating animals. Some do, and I do not claim they are wrong.
Yet veganism isn’t about eating. The eating part is a vegetalian diet. Veganism add to refuse animal’s prduction such as wool, and all kind of human control over animals. And this is the part I can’t see morality in.
Your simple “number will normalize” claim is so scary when given without any thing to back it. Is it to mean you do not care? You want your hands clean and do not care about consequences?
I don’t ask you to eat them. I just ask you to allow them to survive, even when it needs our help. Because that is something we owe them.
That I want, is to step out of capitalism and consumerism in favor of a society that would be organized to support an healthy and happy life to all humans (even those who live far away). For this, I think we (westerners, but not only) need to learn to live with nature instead of against it. Yet since human made self a master of nature, it is their duty to preserve it.
