Stunning images of a chicken embryo slowly developing into a chick living inside a “glass egg” have been shared on YouTube.
Yuri Shevchenko, owner of SlivkiShow’s YouTube channel, spent 3 years trying different techniques for growing a bird in a glass jar.
The Ukrainian vlogger removed the shell of an ordinary chicken egg and placed its contents in a glass jar in a special incubator.
This allowed her to follow and see the development of a chicken embryo from the first heartbeat, until the chick was ready to walk on the table.
The first thing they saw in the jar, Shevchenko said, was the formation of the vascular system, and “it’s a little circle with capillaries that leads to the center of the yolk, where the little heart actually beats,” adding that it was “amazing and amazing how the molecules of yellow know the order in which they line up to form something. Like that. ”
The team started the experiment in 2018, but it wasn’t until this year that they made the right mix of heat and oxygen to allow the fetus to develop.
In a previous video on the same channel, Shevchenko and his team can be seen building a custom Styrofoam incubator.
During the experiment, they used over 300 eggs for a chick to survive through the transparent incubation process.
Each egg was checked for defects, purified, and placed in an incubator while the shell continued to start the development process.
A synthetic wrap was created from duct tape, which has been soaked with a selection of minerals and antibacterial chemicals.

Then, they carefully removed the shell from the eggs that were developing inside the incubator and placed the developing embryo in the new transparent “shell”.
And it wasn’t easy for the Ukrainian blogger, who said it took three years of trial and error to finally get a chick alive.
The vast majority of embryos did not survive, with dozens of different breeds of chickens and hundreds of eggs tested over a three-year period.
Various aspects of fetal development can be observed, including the base of the eye, as well as all limbs.
On the fourth day after implantation in the artificial cortex, the yolk cortex ruptured and spread throughout the developing body.
On the sixth day, the embryos move around the yolk, resembling a small chicken but with huge black eyes in the middle, because “the eye does not change in size during life”.
On the eighth day, the bird moves very actively, which, according to Shevchenko, may be mixing the yolk under the embryo and allowing it to absorb better.
At this point, the neck is thinner, the head protrudes more, and the limbs are elongated, allowing them to bend.
In the wild, a chicken sitting on an egg rotates it every few hours. So the team also repeated this process in a transparent incubator.
And the fetus’ eyes opened on the tenth day and the beak began to appear, according to the video commentary.
It became much darker and doubled in size by the twelfth day, with feathers appearing on the tail and sides.
By day 15, the ear was visible to the left of the large eye, something not seen in feathered chicks.
At this point, the chick begins to receive oxygen, which is usually delivered through the sales process, but since there is no one there, the team provided pure oxygen through a special generator that can produce it. in the required quantity.
The video then moves to day 19, where you see a young chicken taking up most of the space in the cup, with the chick taking up most of the yolk.
The next day, there was hardly any yellow left, there was only one day left, then one morning “I heard a noise in the room”. Then they made him shelter with a table lamp with a special heat lamp to keep him warm and help him survive.
