Colossal hatches 26 chicks from artificial egg using silicone membrane system in breakthrough for de-extinction

Colossal Biosciences/South Island Giant Moa

Colossal Biosciences announced that 26 healthy chickens hatched from an artificial egg using a two-component system: a semi-permeable silicone-based membrane inside a rigid support cup engineered to replicate gas exchange. This breakthrough is foundational for resurrecting extinct birds like the moa and dodo, whose eggs are too large for any living bird to incubate.
