Colossal Biosciences technology uses silicone membrane and lattice structure to support avian embryos outside the natural shell.
An innovation in biotechnology caught attention in May 2026. Colossal Biosciences announced the birth of the first chicks generated in an artificial egg, a shell-less incubation system designed to allow the complete development of avian embryos. According to the company itself, the technology was developed as part of a plan aimed at the de-extinction of the giant moa, a bird extinct for almost 600 years and considered one of the largest to have ever inhabited the Earth.
The proposal was also presented as a potential platform aimed at the conservation of bird species threatened with extinction. The artificial structure combines a lattice shell architecture with a bioengineered silicone membrane, capable of matching the oxygen transfer of a natural shell and maintaining the gas at ambient levels.
Discover the shell-less artificial egg
The system developed by Colossal Biosciences replaces the biological shell with an artificial structure designed to meet the needs of the embryo during incubation. The lattice architecture functions as physical support, while the bioengineered silicone membrane allows the gas exchange necessary for avian development.

The company claims that this membrane can reproduce the oxygen transfer capability of a natural shell. As a result, the embryo remains in a controlled environment, without relying on the traditional protection of a common egg. The innovation drew attention because the birth of the chicks indicates that the system managed to sustain the embryonic cycle until hatching.
The advancement is part of the company’s project to study ways to bring back the giant moa. The bird has been extinct for almost six centuries and is among the company’s main scientific targets in the area of de-extinction. Nevertheless, the birth of the chicks does not represent the immediate return of the species, but a technical step within this process.
In addition to the giant moa, the technology can be applied in studies aimed at the conservation of threatened birds. Colossal Biosciences points out that the artificial egg could become a new platform to support research with species at risk, especially when natural incubation presents limitations.
How technology can impact bird conservation
Currently, the announcement places the artificial egg at the center of a discussion about biotechnology, preservation, and embryonic development outside the natural shell. The creation of the first chicks in this system shows an experimental alternative to monitor avian embryos in controlled conditions.
The technology also broadens the debate on the use of artificial tools in conservation projects. By reproducing essential functions of the natural shell, the lattice structure and silicone membrane indicate a technical path for future research with threatened birds and extinct species.
Thus, the work of Colossal Biosciences transforms the artificial egg into an important piece within a larger project. The system still depends on new scientific stages, but it already stands out for combining shell-less incubation, bird conservation, and studies on the possible de-extinction of the giant moa.
