Story summary

Colossal Biosciences hatched 26 live chicken chicks from a 3-D-printed, shell-less egg platform.
The platform uses a 3-D-printed lattice with a silicone membrane for gas exchange and added calcium.
Executives say it could incubate embryos of species with eggs too large for any surrogate, like the extinct South Island giant moa.
Independent scientists note the system lacks yolk and temporary organs and urge peer-reviewed data before assessing de-extinction relevance.
