Amazing Birth photos of a chicken

Amazing Birth photos of a chicken. 
It is always interesting to watch the beginning of a life. 





















Inside Chicken's Egg


Day - 1. There are not any changes, yet.

Day - 3. On the egg yolk some blood vessels develop which provide the embryo with nutrients                  of the white of the egg and the egg yolk.

Day - 5. You can see the blood vessels, which look like threads.

Day - 6. The blood vessels are getting tighter and look like a cobweb. 

Day - 12.  Within twelve days the embryo develops to look like a ready-made chick, but it only                      uses one half of the egg, so it will have to grow some more during the remaining nine                  days within the eggshell. Surprisingly, it is already able to hear.

Day - 14.  On the picture you see the fetal membrane which is supplied with blood, the yolk, the                    blood vessels running from the yolk to the embryo supplying it with nutrients and the                      breathing membrane.

Day - 17. After the hatching period of 17 days the chick pierces through the egg membrane,                        and when its head and beak are in the air chamber it breathes with its lung. Now it                        perceives the voice of its mother and will remember it for the next few weeks.

Day - 19. The chicks start to communicate with each other and their mother. So actually they                        can control when to hatch out and they can delay it for over two hours until all chicks                      are ready to hatch out. Particularly for wild-living birds this is an advantage, because                    all the chicks get dry together and they can also leave the nest with their mother at                        same time. A short time before hatching out (on the 19th or 20th day), the chick pulls                    the egg yolk through its navel into its stomach, and then the navel locks. So the egg                      yolk can be used as food for the next 24 hours.  

Day - 20.  Although the brood normally takes 21 days, most of the eggs are pecked on the 20th                 day. But actually "pecked on" is the wrong expression, because there is not enough                     room inside the egg to peck. Until a short time before hatching out, the chick's head                     lies on its breast. Then it lifts its head pressing a hole into the eggshell by means of a                   thorn located on the beak. By moving inside all the time the whole eggshell cracks and                 the chick presses against the eggshell. As it lifts the back of the neck it finally opens                     the lid. Important: The hen does not help the chick at all to get out of the eggshell.                         That's why you should not help your chicks either.

Day - 21. Finally the chick hatches out.
