Chickens without eggs? The De-extinction Company creates an artificial egg.

In a way, Colossal seems to have solved a problem that I don’t have anymore (since I’m now a journalist) but maybe it’s a problem for biologists. However, the company did this as an important part of one of its completed projects.

Not all eggs are created equal

Why should they externalize the matter of eggs? It’s going back to the two that were set to disappear, the dodo and the moa. Both species are larger, larger than their neighboring species. In the case of the moa, it is the largest of all birds in existence. If you want to make something this big, then there is no way to remove an egg from an existing species and insert an embryo into it. So, one of Colossal’s next steps is to see if it can supplement the egg – do things like add enough nutrients to the yolk to support the growth of a large embryo.

This cannot be done before the embryo is set, because spraying too much into the yolk can cause the membrane inside to burst. Instead, they have to add or exchange things as the embryo grows.

Another issue they have to deal with is that embryonic development begins while the egg is still inside its parent. So the group will have two choices. One option is that they will need to figure out how to make the first half of the developmental day go without an egg, and transfer the embryo into an egg. Instead, they will have to figure out how to use the eggs after they are transferred to the device.

But some of them are problems of ending. For any researchers who think this could benefit their career, the company would love to hear from you. “I’m sure there will be labs that want to use this for research, which is great,” Lamm told Ars. “Also, we don’t pay for anything, we just give.”
