Artificial egg hatched 26 healthy chickens
Colossal Biosciences has successfully hatched 26 healthy chickens using its innovative artificial egg system. This breakthrough is seen as a significant step towards the company's goal of resurrecting extinct bird species. The artificial egg utilizes a silicone membrane to facilitate gas exchange, addressing challenges faced by previous hatching systems.
- ▪The artificial egg system is designed to replicate the gas-exchange function of a natural eggshell.
- ▪Previous shell-free hatching systems struggled with low success rates and required concentrated oxygen, risking DNA damage.
- ▪Colossal's approach involves transferring viable embryos from real hen eggs into the artificial egg for incubation.

The Colossal Biosciences artificial egg — a silicone-membrane synthetic shell system — successfully hatched 26 healthy chickens, the Dallas-based de-extinction company announced on May 19, 2026. Colossal Biosciences describes the breakthrough as a foundational step toward its goal of resurrecting extinct bird species, including New Zealand’s South Island giant moa and Mauritius’s dodo. What the Colossal Artificial Egg System Is The Colossal artificial egg is a two-component system: a semi-permeable silicone-based membrane housed inside a rigid hexagonal support cup. The membrane is engineered to replicate the gas-exchange function of a natural eggshell — allowing oxygen to pass through while retaining moisture and blocking contaminants.
