Colossal Biosciences is growing chickens in a 3D-printed container

The baby chicks were shifting and starting to pip—or trying to hatch.

The biotech company today claimed it has developed a “fully artificial egg” as part of its effort to resurrect extinct avian species, including birds like the dodo and the giant moa.
