Egg prices have surged dramatically in recent months, driven by a combination of bird flu outbreaks, rising production costs, and new state regulations on how hens are housed. If you’ve noticed eggs costing $5 to $10 a dozen depending on where you live, you’re not imagining things. A few overlapping forces explain why.
Some searchers may also be wondering why eggs are high in cholesterol or nutrients. That’s covered below too, since eggs pack a surprisingly dense nutritional profile into a small package.
Bird Flu Is the Biggest Price Driver
The highly pathogenic avian influenza virus, H5N1, has forced U.S. poultry farmers to cull more than 150 million chickens since January 2024. When a flock tests positive, the entire operation is typically depopulated to contain the spread. That’s an enormous hit to the nation’s laying hen population, and it takes months for farms to restock and return to full production.
The result: egg supply is roughly 7 to 10% lower than it would be without those losses. That gap between supply and demand has pushed retail prices as high as $9 a dozen in some areas, with grocery stores periodically running out between wholesale shipments. Even a modest supply shortage in a product this widely consumed creates intense price pressure at the register.
Cage-Free Laws Add to the Cost
Since 2018, California, Massachusetts, and close to a dozen other states have adopted laws requiring that all eggs sold within their borders come from cage-free hens. These housing systems give birds more space and freedom of movement, but they cost more to operate. Labor costs alone can triple compared to conventional cage systems, and feed costs run about 2.6% higher in aviary-style barns.
The price difference is visible across state lines. In January, a dozen eggs cost $6.29 in Royal Oak, Michigan (a cage-free mandate state), while just over the border in Toledo, Ohio (no such law), eggs were under $4. In California, prices have approached $10 a dozen, nearly double the national average of just under $5. A study in the American Journal of Agricultural Economics estimated that California’s cage-free law alone would cause annual welfare losses of $72 million for households in the state.
Nevada took the unusual step of building an emergency clause into its cage-free law, allowing the mandate to be temporarily suspended for 120 days during supply crises. The federal Department of Agriculture has also signaled interest in examining whether state-level cage-free mandates are contributing to price volatility.
Feed, Fuel, and Labor Costs
Beyond bird flu and regulation, the basic inputs for egg production have gotten more expensive. Hens eat corn and soybean meal, and those commodity prices have fluctuated significantly in recent years. Energy costs for heating, cooling, and lighting barns factor in too. These aren’t dramatic headline-makers like avian flu, but they form a steady upward baseline that makes eggs more expensive to produce regardless of flock size.
Why Eggs Are High in Cholesterol
If your search was about nutrition rather than price, here’s the short answer: one large egg contains about 186 milligrams of cholesterol, all of it concentrated in the yolk. Egg whites contain zero cholesterol. That 186 mg figure made eggs a dietary villain for decades, but the picture has shifted considerably.
For most people, the cholesterol you eat has only a modest effect on the cholesterol circulating in your blood. Your liver produces the majority of your blood cholesterol and adjusts its output based on what you consume. Eat more cholesterol, and your liver typically dials back its own production. This internal regulation means a daily egg doesn’t move the needle much for the average person. The American Heart Association supports consuming up to one whole egg per day as part of a healthy dietary pattern for people with normal cholesterol levels.
There’s an important exception. Some people are “hyper-responders,” meaning their blood cholesterol rises and falls strongly in response to dietary cholesterol. For these individuals, limiting cholesterol-rich foods can make a real difference. If you have high cholesterol or heart disease, it’s worth knowing whether you fall into this category.
What Makes Eggs So Nutrient-Dense
Eggs are high in more than just cholesterol. They’re one of the richest dietary sources of choline, a nutrient essential for brain function and nervous system signaling. A single yolk provides about 115 mg of choline, more per serving than milk or most other common foods. Most people don’t get enough choline from their diet.
Yolks also contain lutein and zeaxanthin, two antioxidants that protect eye health and are the only carotenoids capable of crossing into brain tissue. They accumulate in the retina and the brain, where they play a role in both vision and cognitive function. Eggs also supply DHA, an omega-3 fat linked to brain development, along with B vitamins, vitamin D, selenium, and iron.
On the protein side, eggs are essentially the gold standard. Their protein digestibility score is a perfect 1.0, matching whey protein and casein. This means your body can absorb and use virtually all of the protein an egg provides. One large egg delivers about 6 grams of complete protein, containing all the essential amino acids in proportions your body can readily use. For a food that costs (even at today’s inflated prices) well under a dollar per serving, eggs remain one of the most efficient sources of high-quality nutrition available.
