World’s Most Advanced Artificial Egg Hatches Chicks [Video]

BREAKTHROUGH: De-Extinction Just Got Its Egg

Step inside the beginnings of life as Colossal Biosciences hatches live chicks from our new artificial egg.

This huge advancement is foundational to our de-extinction of the South Island giant moa, whose eggs were around 80x the volume of a chicken’s. No living bird could possibly hatch one. So we built an artificial egg that will.

Watch a real chick embryo develop inside the artificial egg. Get a full breakdown of every feature. And see how this breakthrough is opening new doors for avian biotech research and bird conservation.

You’ll want to see the ending.

Meet the Colossal artificial egg. Nature spent millions of years perfecting the original. We just made our own, and hatched some beautiful and healthy chicks. Here’s how it works:

🥚 Egg-shaped frame: a lattice shell that gives the whole system its structure and protection.

🌬️ Colossal membrane: the secret weapon. A bioengineered, gas-permeable layer that matches a real shell’s oxygen transfer, so O₂ flows in and CO₂ flows out exactly the way nature does it.

👁️ See-through build: the largely transparent design that lets us watch development in real time. This is critical for research and for de-extinction, where visually confirming milestones and the gene-edited traits we’ve put back is everything.

📏 Modular scale: the platform will stretch to fit eggs of any size, including the South Island giant moa egg, roughly 80x the volume of a chicken egg.

Extinction doesn’t have to be the end. And this is just the beginning. Avian de-extinction is getting wild.
