Welcome to Part 2 of our myth-busting series on the egg industry.
In Part 1, we tackled common misconceptions about hens and eggs. Now we’re exploring myths about hen biology, manipulated living conditions, and misleading marketing claims, such as “hens naturally lay eggs daily,” or “dark yolks indicate better welfare.”
If you've ever wondered how “natural” eggs really are, keep reading.
5. “Only happy hens lay eggs.”
This common belief sounds comforting, but it’s misleading.
Laying eggs is a biological function, not a reliable indicator of wellbeing. A hen may continue to lay even when her body is under immense stress. This is because hens have been bred to be highly productive, and their physiology allows them to keep laying despite poor conditions.
In commercial farms, hens face constant stress—from overcrowded barns, rough handling, and noise to sudden changes in temperature, light, or feed. These stressors can cause hormonal spikes or chronic health issues like weakened bones and suppressed immune function. Yet many hens keep laying through it all due to a process called allostasis: their bodies adapt to stress to maintain egg production—even when it takes a toll.
Egg output doesn’t mean a hen is thriving. In fact, hens in less stressful backyard environments might lay fewer eggs but live much longer and healthier lives. Meanwhile, commercial hens might keep laying while silently suffering from parasites, poor nutrition, or reproductive exhaustion.
The bottom line: consistent egg laying is not a sign of happiness or good health—it’s often a sign of survival in a system that prioritizes output over wellbeing.
6. “Hens lay an egg every day—it’s the most natural food to eat”
The egg industry likes to suggest that daily egg-laying is simply what hens do. It sounds natural, even effortless. But this image is far from the truth.
Today’s hens are the result of decades of intense selective breeding. While their wild ancestors laid around 12 eggs per year, modern hens have been engineered to produce between 250 and 330 eggs annually. In some cases, industry breeding targets push for as many as 500 eggs per hen in a single laying cycle.
This level of output is anything but natural. It puts enormous strain on the hen’s body and leads to serious health issues, including osteoporosis, skeletal depletion, and reproductive tract problems. After just 72 to 100 weeks of this exhausting cycle, the hens are considered no longer profitable and are sent to slaughter.
The truth is, hens do not lay eggs every day because it is natural. They do it because they have been genetically manipulated to meet the demands of a system that sees them as egg-producing machines.
What we call “natural” is actually the result of extreme intervention in their biology.

7. “Hens need sunlight to lay eggs—egg farms are bright places.”
The industry loves to show sun‑drenched barns, giving the impression that hens bask in natural daylight. In reality, sunlight is not required. What matters is control.
Hens are photoperiod‑sensitive birds; their bodies start an egg‑laying cycle when they receive roughly 14 to 16 hours of light. Farmers replicate spring and summer by flipping on low‑watt bulbs and setting them on a timer. No sun needed—just electricity.
Most barns run at 10 to 20 lux, about as bright as a dim hallway closet. A sunny day outside reaches over 80 000 lux. In these gloomy sheds, dawn and dusk are faked, and red or orange lights are sometimes added to stimulate reproductive hormones. The goal is simple: more eggs, more quickly, with little regard for the toll on the hens’ bodies.
This artificial schedule keeps hens producing nonstop while masking the harsh, cramped reality inside the barn. Bright marketing photos do not match the dim truth.
8. “A dark yolk means a hen is happy and healthy.”
Egg cartons often feature deep, vibrant yolks to suggest freshness, better taste, and healthier hens. This appealing imagery, however, is purely marketing.
Egg yolk color mainly depends on diet—specifically, carotenoids from plants like corn, carrots, or alfalfa. In nature, these pigments produce a range of yolk shades from pale yellow to deep orange. But egg producers commonly add natural feed additives to achieve consistently dark yolks for consumer appeal, regardless of actual hen wellbeing or egg quality.
In fact, yolk color does not reliably indicate better nutrition, superior taste, or humane living conditions. Even hens confined in cages can produce eggs with deep-colored yolks if their diets include certain pigments.
Ultimately, yolk color is a manipulated illusion, created by producers to mask cruel practices and boost consumer appeal—not evidence of happy or healthy hens.
The egg industry carefully shapes the way we see hens, eggs, and farming practices. From controlling light exposure to force egg production, to adding pigments to feed to influence yolk color, much of what we are told is a marketing illusion.
These systems are not designed to support animal wellbeing. They are designed to maximize profit, often at the cost of the hen’s health and life.
Once we begin to question what we’ve been taught, the truth becomes hard to ignore. Hens are not machines, and eggs are not a harmless food. They are the product of a system built on control, manipulation, and suffering.
If we want a kinder world, it starts by leaving eggs off our plates.
