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.

    Before capitalism, people used to only kill as many animals as were necessary to feed them, all while ensuring they don’t suffer needlessly and respecting their natural habitats.

    Under capitalism, animals are just resources to be extracted and turned into products and profits. The conditions of this extraction may vary slightly, but ultimately this is never going to change under a system that fundamentally removes humans from nature, as well as focuses on accumulation of capital above all else.

    I am looking forward to the day that cloned meat is an thing. It would likely save on resources, be more sanitary, and would prevent the suffering of animals for our pleasure.

    However much I enjoy my chicken tenders, I would like less awful to be involved for getting them onto my tastebuds.

          What happens to hens when their production slows down? The eggs that are fertilised to replace the hens who die, what happens to the male chicks? Are these chickens frankenchickens who produce 1-2 eggs a day, or are they more natural chickens who will produce an egg once a month or so? because laying so many eggs is brutal on their bodies. Since you seem like you’re a woman with name like Jessica, imagine cycling everyday for your entire life. That’s what these frankenchooks have to deal with.

          If you purchase meat from these companies - you very much do.

          If you don’t want to - there’s an extremely obvious solution available.

          Ultimately all manner of meat consumption in industrial societies amounts to genocide and torture. All we’re doing is slightly negotiating the degree of suffering inflicted.

            Veganism means we don’t give a space to farm animals anymore. We (humans) have modified them in such way they can’t survive in nature ; especially in the few nature we would let them. How can it have an other result than the genocide of all that species?

            Industrial exploitation of animals count as torture and should be stoped for that, yes. But it is not a genocide: it makes sure the species remain alife. The genocide is vegan.

            Welfarism seems to me the research of the best compromise: keep that species alife and in better conditions.

        An all or nothing stance is part of the problem though. If doing good is defined in a way that is difficult for people to achieve, they will feel like they can’t do good and give up before they started.

        Anything we do to improve the lives of animals or remove some suffering does exactly that.

            It is difficult to get adequate nutrition on a vegan diet.

            It requires being able to read about nutrition and putting that knowledge into practice - which involves making meal plans that take into account the various mineral and vitamin requirements that we have in order to be healthy.

            There are significant accessibility barriers when it comes to eating a healthy, vegan diet.

            It is not an easy feat for the abled, and in addition there are factors such as socio-economic status and associated challenges that can make it less accessible for people.

              It is difficult to get adequate nutrition on a vegan diet.

              It is not. Eat your legumes, beans and some nuts and look for B12 fortified foods. That’s it. Keep in mind that most people are unhealthy on non vegan diets, and that meat is fortified with B12 too because the animals don’t get it in nature. So it’s but a small change for an equal nutritious diet.

              It requires being able to read about nutrition and putting that knowledge into practice - which involves making meal plans that take into account the various mineral and vitamin requirements that we have in order to be healthy.

              Again, not really. Same counter argument as before.

              There are significant accessibility barriers when it comes to eating a healthy, vegan diet.

              This is true. Fast food becomes hard to find, so you’ll have to actually start cooking now and then, which is something a lot of unhealthy non-vegans are scared of. Besides that everything is already available in every first world country supermarket.

              It is not an easy feat for the abled, and in addition there are factors such as socio-economic status and associated challenges that can make it less accessible for people.

              It is an easy feat. But you are correct about your “status” in society. You’ll often get people trying to argument against being vegan. And those are all the same arguments you’ve heard thousands of times, all of which have long been disproven. They’ll tell you you are unhealthy and that it’s hard, but it’s easy and you’re more healthy than them. You get people coming up with arguments not because they believe them, but because they want to believe them, so it justifies their own non-animal-friendly diet. It can be hard, but only because other people make it hard like you do.

                I don’t make it hard. I would love it, if it were easier, but unfortunately it isn’t.

                It is difficult to get the adequate nutrients on a vegan diet. Research the required nutritional values for your age, gender and body type. Type the values into a nutritional application and track your food intake throughout a certain period, the longer the better. With no diet planning on a vegan diet, it is unlikely that you will get adequate nutrition.

                It’s true that people who do not adhere to a vegan diet can be unhealthy. The difference is that their diet does not set them up to be unhealthy if they eat healthy ingredients and do not plan their food intake. If you are vegan, don’t plan your meals on the basis of nutritional knowledge, and only eat otherwise healthy ingredients, you are still at risk of becoming unhealthy because of malnutrition.

                You come off as someone who is generally privileged and has no respect for the different barriers that people face.

        Modern day agriculture is reliant on livestock to keep our current levels of farming efficiency. Farming aimals is a requirement for modern agriculture.

        We just eat to much meat, eating no meat at all will cause so much more problems than veganism would solve.

      Signs of stress, and behaviors that indicate a normative state.

      Chickens, when calm and with their flock, make all kinds of sounds and exhibit behaviors like “cuddling”, and even the rare mutual preening. While it’s impossible to point to anything like that and be 100% certain you’ve identified the internal emotional state of an animal, it’s one of those duck things, only chickens. If it looks like a happy chicken, and trills like a happy chicken, might as well say it’s a happy chicken.

      If chickens don’t get good rest, you’ll notice all the usual bird stress behaviors appearing. Feather plucking, grumpiness, pecking, angry zipper noises, etc.

      So, again, it’s foolhardy to apply human states of mind to anything that can’t speak our language. But some things can be observed and extrapolated to at least be similar.

      Side note: the sound a happy chicken makes when cuddling you will either melt your heart, or prove you’re an emotionless wreck. I have wept at that sound

    FYI caged hens are no longer common in large parts of the western world and even in the worst countries, like the US, the percentage of caged hens have dropped under 50%. For meat chickens it’s even better with practically zero in cages.

    Talking about lightning the EU mandates 6 hours of darkness. Don’t know the US rules. I’m assuming it’s much worse there as it usually is.

      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.

      Please don’t fall into the ‘cage free is fine’ delusion, because putting so many chickens in a square meter that none of them have personal space is probably about as miserable for them as being in a cage. If anything it can be worse, since chickens can and will attack and eat injured chickens.

      cows in dairy, and chickens in egg are abused horribly as well. Go vegan.

      edit: Egg layers are often in cages, with 3-4 other birds. In a tiny cage. They have no solid ground to stand on, just bars. So their feet are often horribly deformed. When eggs are hatched, if they’re male, they’re killed at less than a few minutes old, because they are “useless” and will never lay eggs. the male chicks will be ground up alive in something called a macerator (think a blender). if they’re born female, they’ll often end up in the same cages as their mothers. They get their beaks chopped off because they will attack each other from all the suffering. Egg layers in the wild will lay 10-12 eggs a year. They’ve been selectively bred so much that they now lay 1-2 a DAY. That’s 300-400 a year! Imagine ovulating every fucking day, often multiple times a day. It’s torture on them. Egg layers can live for 5-10 years naturally, but because laying 300-400 eggs a year is so horrible on their bodies, they collapse and are then slaughtered (sometimes they just dump them in a hole, and cover it up. While they’re alive). Even in “free range”, there are so many chickens in the shed that their pecking order is severely fucked up. Chickens would normally live in a community of a few birds. In these sheds, they’re crammed in by the thousands. The ammonia from all the urea is so strong it burns their eyes and throat etc. It’s truly truly horrible. Activists have to go in to these sheds with breathing masks because the ammonia is so strong. Chickens are bred and fed so fast to have as much meat as possible as quickly as possible that a lot of chickens will break their legs and collapse or have heart attacks (or both). These chickens will then just lay on the ground and starve to death because they are unable to walk to food.

      Also, like all mammals, cows need to be pregnant to give milk. They do not just naturally produce milk all year round (well, dairy cows do, because they’re constantly impregnated, so they give milk nearly all their lives). When the mama cow gives birth, her child will either be killed at a few hours old (if male), or be put into slavery like her mother if she’s a girl. They can live for upwards of 20 years when given the chance, but dairy cows will be slaughtered for low quality meat such as sausages and burgers at just 3-4 years old. Imagine being pregnant almost all your life. Shit is terribly hard on their bodies. When cows cannot do it anymore, they just collapse. These cows are called “downers”. They are dragged out by a truck/forklift by their legs. Then slaughtered.

      Imagine your life being so worthless that you’re mistreated for all your life, only to then become a fucking burger or nugget. Holy shit.

      It’s suffering all the way down.

          Yup. The pine for weeks or even months sometimes for their children. They can hear them. They may even be able to see them, but they can’t get to them, because milk. Mammals are incredibly maternal. Imagine having baby after baby being taken from you minutes after birth, never to see them again. Again, suffering all the way down.

          There is a mother cow on a sanctuary here in australia (clarabelle). She was rescued from the dairy industry when she was pregnant. She gave birth to her son (valentine, because he was born on valentine’s day). When he was a youngin, Clarabelle would hide him from the workers at the sanctuary, probably because she was afraid he’d be taken from her. She did this for months. Every time the workers would find Valentine, she’d move him. It was heartbreaking.

          FYI, the farm is called Edgar’s Mission.

          Remind me again how animals don’t have feelings and emotions, and are just unthinking automatons?

      if you want to make an impact on the suffering of animals, veganism is it. vegetarians still support the dairy and egg industries, which may be the most cruel.

        I see, I guess I need to look more into it. Every time I try I rage quit because it’s so infuriating.

          You don’t need to know about the meat industry horrors or the health impacts of meat or benefits of less meat. Just make small changes like finding dairy alternatives you like, or a meatless recipe you like. From there you can continue to make as few or many additional changes as you like.

          Start with something. Being vegan is still hard to do in many places. Being vegetarian is thankfully much better than it was 30 years ago.

          Back in the day I once traveled the entirety of a certain midwestern state where my food options were essentially coffee and salad. I mean, not really, but also kinda. It’s better now.

              FYI, there are a fair number of vegan communities who are MORE than willing to help you go vegan. Reach out to them if you have any questions.
