It keeps it safe while it develops. The yolk is food for the chick.
It develops until it's ready to hatch.
A young chick develops inside the egg and can be hatched naturally or through hatcheries. The young chick depends on the egg yolk for nutrients.
it all develops into into the chick many different ways. For example, when the YOLK develops into a chick it is very interesting how i does!!
the chick develops on the edge of the egg yolk (the yellow part) as it grows, the chick absorbs the nutrients from the yolk into it's body as food.
Yolk is the nutrients that nourish the chick as it develops.
it means the pictures in front are of a chick a chicken and an egg you have to step onto the different pictures in the correct order of their life so an egg thent he chick then the chicken and then the egg again and it continues like that
Yolk is the nutrients that nourish the chick as it develops.
The developing chick feeds on the yolk sac, much like the baby of live bearing animals attaches to the placenta. The chick has enough nutrients when born to got 24 hours without beginning on chick starter.
As the forming chick develops the nutrients and moisture used up by the chick inside the previously full egg is replaced by air. This air is allowed into the egg because the eggshell is porous. The air gathers at the end of the egg. You can see the results of this air transfer when you put a stale egg into a bowl of water, the egg floats at one end. This accumulated air is used by the chick as it starts to peep or break open the shell the day it hatches.
A baby chicken has a rather short history. When it comes out of the momma chicken as an egg it takes only 21 days for that egg to be formed into the chick. From the day that chick exits the shell, it walks and eats and learns to live on its own. Follow the link provided and see how the chick develops.
All eggs have an air pocket inside the egg the chicks beak will be slightly inside of the pocket. As the chick develops further the air pocket gets bigger. This is normally the same for reptiles and any other animal that produces eggs.
