Scientists Hatch Live Chicks From Artificial Eggshells in De-Extinction Breakthrough

The idea sounds almost impossible: a chick developing without a normal eggshell. But that is exactly what de-extinction company Colossal Biosciences says it has achieved, hatching 26 live chickens from a 3D-printed artificial shell system.

The breakthrough is not the return of an extinct bird yet. It is a technical step that could help solve one of the hardest problems in bird de-extinction: how to grow embryos when no living bird can lay or carry the right kind of egg.
