We've reported on this topic before, and now it's come back into focus thanks to a newly uploaded video on Facebook from April 2023 with over 2 million views. This video shows how a chick grows in an already opened egg. Inquiring users suspect that this video is fake, but that is not the case! Anyone who has always been fascinated by the growth of a chick in an egg can watch it impressively in this time-lapse video.
The fascinating chick video, which lasts around a minute, impressively shows how an egg is carefully opened, the contents carefully removed and processed before being placed back into the open egg. As the video progresses, you witness the chick's impressive development and can finally marvel at how it emerges alive from the opened egg.
Surprisingly, the video does not come from a research laboratory, but from Japanese students. They show how a chicken hatches from a chicken egg through artificial insemination.

There are even detailed instructions on how to raise such a chick. In a previous article we referred to Professor Yutaka Tahara and Dr. Katsuya Obara from Takanedai Animal Clinic. The two developed this method and wrote a detailed document that describes the exact process and methodology ( HERE ).
Chicks in an open egg: how it works
However, you have to be prepared for possible losses because the survival of the chicks is not guaranteed. Although 90 percent of the embryos survived until day 17, even aeration with pure oxygen from day 17 only led to a hatching rate of 57.1 percent.
However, there is a scientific purpose behind the seemingly playful experiment: chickens are better suited than laboratory mice for studying certain genetic defects. Chicks with genetic defects could be bred in glass and examined at the embryonic stage in order to identify possible treatment methods. Stem cell research on chicken embryos is also conceivable. It is generally banned in Germany, but is allowed in chickens because they do not feel pain until shortly before hatching, according to Professor Michael Lierz from the University of Giessen.
The experiments are also interesting for species protection: If the method is one day perfected, bird species threatened with extinction could be preserved through artificial insemination in the laboratory. Although the video looks simple, it involves considerable effort.
