From dodo to dinner plate: what 26 chicks in artificial eggs really mean

When 26 fluffy chicks pecked their way out of clear, 3D-printed shells in a Texas laboratory, the headlines naturally gravitated to the most cinematic part of the story: a company that wants to bring back the dodo had just hatched birds without an eggshell. But strip away the de-extinction theatrics and the Colossal Artificial Egg System is something arguably more consequential — the first real proof that a chicken can develop, from blastoderm to hatch, inside a vessel humans designed from scratch.

For a country like Australia, where poultry is the most-eaten meat and the egg industry produces billions of eggs a year, that proof-of-concept opens doors that go well beyond saving extinct birds. It hints at a future where incubation itself becomes an engineered, observable, and editable process.

What Colossal actually built

According to Colossal Biosciences, the Artificial Egg System (AES) is a transparent, 3D-printed shell paired with a tightly controlled environment that mimics the chemistry, gas exchange and temperature gradients an embryo would normally experience inside a hen's egg. The company describes it as an “ex ovo” platform: the embryo grows outside a natural shell while still receiving the yolk, albumen and membranes it needs.

Reuters reports that the Dallas-based company — better known for its woolly mammoth and dodo de-extinction ambitions — used the system to hatch live, healthy chickens, which it is treating as a stepping stone toward incubating bird species whose eggs are either unavailable or too fragile to work with. National Geographic, which photographed one of the chicks, framed it as the first time a bird has hatched from a fully artificial egg.

Vice's account adds the figure that's been circulating: 26 chickens were grown to term inside these printed eggs. That number matters. One hatch is an anomaly; 26 is a process.

Why incubation is the bottleneck

Commercial poultry already relies on industrial-scale incubators — warm, humidity-controlled cabinets that turn thousands of fertile eggs at once. But every one of those eggs is still a black box. Producers can candle them to see rough silhouettes, but they can't watch a heart form, intervene when something goes wrong, or sample the developing embryo without destroying it.

That opacity is expensive. Hatch rates in commercial broiler operations typically sit somewhere between 80 and 85 per cent, meaning roughly one in six fertilised eggs never produces a viable chick. Multiply that across a national flock and the losses are enormous. A transparent, instrumented egg — the kind Colossal has demonstrated — is, in principle, a window into exactly where and why those failures happen.

It also changes what's possible upstream. If embryos can be monitored continuously, breeders can:

The food-production angle Colossal isn't selling

Colossal's pitch is conservation: as Reuters notes, the company wants to use the AES to incubate eggs of endangered or extinct bird species, where you simply cannot afford to waste a clutch. But the technology it has built is, functionally, a programmable bird factory at the scale of a single embryo. That has obvious implications for the protein industry.

Consider three plausible flow-on effects:

1. Smarter, faster genetic improvement

Modern broiler chickens already grow to slaughter weight in around 35–42 days, the product of decades of selective breeding. The next gains — in disease resistance, feed conversion, welfare traits — increasingly come from genomics. An artificial egg that lets researchers observe, sample and modify embryos without killing them dramatically shortens the feedback loop between a genetic hypothesis and a living bird.

2. Biosecurity and disease control

Avian influenza outbreaks have hammered egg supply in the United States, Europe and, more recently, parts of Australia. A sterile, sealed incubation environment with full atmospheric control isn't a silver bullet, but it removes one of the dirtiest stages of the production chain — the breeder hen and her shell — from the equation. For specialist flocks (pathogen-free birds used to make vaccines, for example), that is genuinely valuable.

3. A bridge to no-kill and cultivated alternatives

The Artificial Egg System is not lab-grown meat, and Colossal hasn't suggested it should be. But it sits in the same intellectual neighbourhood: take a biological process that used to require an animal's body and run it in a bioreactor instead. If you can grow a whole chicken in a printed shell, the engineering knowledge that gets you there — oxygen diffusion, nutrient delivery, waste handling — transfers directly to cultivated-meat work and to in-ovo sexing technologies that aim to end the culling of male layer chicks.

What it doesn't mean

It's worth being blunt about the gap between a 26-chick proof and a transformed food system. A 3D-printed shell is, by every available account, vastly more expensive per egg than the one a hen produces for free. Vice's coverage makes clear this is still very much a research platform, not a production line. Scaling from boutique research apparatus to the tens of millions of eggs Australian hatcheries put through each year is a different problem entirely — one of cost, throughput and regulatory acceptance, not just biology.

There's also a values question. Australian consumers have spent the past decade pushing the egg industry toward free-range and away from cages. A future in which chickens are grown entirely outside a mother bird's body is not obviously the direction shoppers in Coles or Woolworths are asking for. The same technology that could end male-chick culling could also be read as one more step away from animals as animals.

The bigger picture

The most honest framing of Colossal's announcement is probably this: a company chasing the dodo has, almost as a side effect, built one of the most useful research tools commercial poultry science has seen in years. The 26 chickens themselves are unremarkable — they look, behave and presumably taste like any other chook. What's remarkable is the shell they came out of.

For a country whose food security depends heavily on resilient, disease-resistant poultry, and whose conservation agencies routinely struggle to breed threatened native birds in captivity, both ends of that spectrum matter. The artificial egg is, for now, a curiosity. But like the first incubators of the 19th century, which let farmers stop relying on broody hens, it's the kind of curiosity that quietly rewires an industry once the price comes down.

Twenty-six chicks is not a revolution. It's a receipt.
