Info from Licensor: "This video is of a one-week old cockatiel egg undergoing incubation. The video was taken on May 2nd, when I was checking for my cockatiel’s eggs fertility. This is done by shining a strong light (Phone light is enough) to make sure the chicks are developing. To my surprise, the chicks were not only developing already, but they were very active and lively as well. In the video, one can see the red network of veins, the yolk sac and the chick moving. Its beak and eye can be seen starting to form. Since this was a week old egg (out of 3 weeks of incubation), the embryo is not fully developed and is quite see-through, making the visual much more fascinating."
