Live chicks hatched from artificial eggshell, biotech company says

U.S. Live chicks hatched from artificial eggshell in bid to revive extinct 12-foot bird, biotech company says May 19, 2026 / 10:54 AM EDT / CBS/AP Add CBS News on Google A biotech company that aims to resurrect lost creatures said Tuesday it has hatched live chicks in an artificial environment — a development that was met with mixed reviews from scientists and critics of its de-extinction mission.Twenty-six baby chickens — ranging from a few days to several months old — were born from a 3D-printed lattice structure that mimics an eggshell, according to Colossal Biosciences.Colossal previously announced it had genetically engineered living animals to resemble extinct species, including mice with long hair like the woolly mammoth and wolf pups that take after dire wolves.Colossal's CEO Ben Lamm said the artificial egg technology could one day be scaled up to genetically tweak living birds to resemble New Zealand's extinct South Island 12-foot giant moa, whose eggs are 80 times the size of a chicken's and would be difficult for any modern bird to lay."We wanted to build something that nature has done a pretty good job of developing and make it better and scalable and even more efficient," Lamm said.The company released images and video showing scientists carefully handling the chicks.Independent scientists say the technology, while impressive, lacks some components to be truly considered an artificial egg. And they said the idea of reviving extinct beasts is likely impossible. "They might be able to use this technology to help them make a genetically modified bird, but that's just a genetically modified bird. It's not a moa," said evolutionary biologist Vincent Lynch with the University at Buffalo.
