A group of Japanese high school students have grown a chicken from an egg without a shell.
The teenagers, from Chiba in Japan, with their teacher demonstrated the method using a plastic cup and cling wrap.
And the scientific experiment works over a period of 21 days as a video posted on Youtube shows.
In the video, students are seen cracking fertilized eggs into cling wrap filled with a chemical solution to aid growth suspended above the bottom of the cup.
Another solution to help development is also placed at the bottom of the cup and a plastic cover is placed on top of it before it is placed into an incubator.
Over the course of the video, viewers see a chicken’s heart starting to grow on the third day and an embryo beginning to take shape on the fifth day.
A week later, the veins of the embryo have spread through the yolk.
As more days go by the chick gains more limbs such as its feet and its beak.
In the footage filmed on Day 21, a curled-up baby bird is seen in the cling wrap.
The video then cuts to a baby chick running around on the floor.
Although the video claims it is ‘the first time in history,’ this is not the first time the technique has been demonstrated.
For years, scientists have been trying to find a way to gain access to baby chicks during development, not only to learn about the growth process, but also to study new regenerative medicine techniques.
In a chapter in a US biology textbook from 1993, Dr Cynthia Fisher explained how to use the technique among groups of students.
The paper describes the method for obtaining a 70 per cent hatch rate, it says.
‘What is shown [in the video] is feasible although the success rate may be low,’ Professor Nick Sparks, head of the Animal & Veterinary Sciences (AVS) Group at Scotland’s Rural College told MailOnline.
‘The experiment seems genuine as the method was previously published in a scientific journal called Journal of Poultry Science which is published in Japan,’ Professor Ilias Kyriazakis from Newcastle University told MailOnline.
