In this video series, the experimenters incubate chicken eggs in a glass to observe the stages of development of the chicken embryo. They record and present interesting images from the experiment over three years, including the formation of the vascular system, the body of the embryo, and the growth of limbs, feathers and claws. They also encountered many failures, but with adjustments to the composition and concentration of the solution and the amount of oxygen, one chick successfully hatched. They provide shelter and care for the chick and ask for name suggestions from their viewers.
1. A chicken egg was poured into a glass and placed in a special incubator for an experiment.
2. The experiment aims to observe the stages of development of a chicken embryo.
3. The video was edited from three years of recorded footage.
4. The first observed development was the formation of the embryo's vascular system.
5. The embryo's heart is approximately one millimeter in size.
6. The heart and blood cells could be visibly seen moving through capillaries.
7. By the third day, the contours of the embryo, including eyes and limbs, were visible.
8. On the fourth day, the yolk shell breaks and spreads over the protein.
9. Vessels and capillaries transport nutrients from the yolk to the embryo, aiding its growth.
10. Not all embryos survived the entire incubation period.
11. Over three years, hundreds of eggs from dozens of different chicken breeds were tested.
12. On the eighth day, the yolk membrane with capillaries occupied more than a third of the yolk surface.
13. The embryo's movement is thought to mix the yolk, improving nutrient absorption.
14. In nature, hens turn eggs every few hours, so the incubator was angled and rotated to mimic this.
15. By the tenth day, the embryo's eyes had opened.
16. By the twelfth day, the embryo had almost doubled in size and had feathers on the tail and sides.
17. Blood vessels in the embryo were significantly larger by this point.
That's a condensed rundown for ya.
