After around 7-10 into the incubation period, (research this to check), it is possible to do something called candling. Candling is where you shine a light into the egg and look at the embryo forming. If there is nothing and the egg is clear, then the egg is infertile. If there is an opaque object in the egg, this is an embryo. Be careful though, because if you candle early in the incubation period you might be unable to see the embryo yet and mistake it for an infertile egg! When you choose a candling torch, make sure it's not one that releases a lot of heat because this could damage the chick. Good Luck!
The yolk of the egg is food stored for the chick during its growth.
When the chicken haches.You can't tell if the chick is growing by just whatching.To see if the egg is growing,hold it up to a bright light.If the egg is fertile,it will have a dark spot in the center indicating that tha chick is growing.If the egg is infertile,it will be somewhat clear(eat it).This practice is called candling.
You can explain to the child that a food egg, like the ones we eat, comes from a hen and is just an egg that doesn't have a baby chick inside. In contrast, a baby chick egg has a tiny chick developing inside it, which will eventually hatch into a baby chicken if it is kept warm and safe. So, one is for eating, while the other is for growing a new chick!
They both do. The yolk acts as a food source for the growing chick, providing not only proteins and fats but sources of minerals as well important to a growing chick's body.
There is nothing different if you are talking about a live egg as there is a chick growing in side of it. a fertile egg is when the daddy rooster make the egg fertile
inside an egg, the white part provides food for it. the chicken itself grows in the yolk.
Before you eat an egg, the chick develops inside the egg if the egg is fertilized. It goes through various stages of embryonic development, growing organs and tissues until it's ready to hatch. If the egg is not fertilized, it does not contain a developing chick and is simply a food product laid by the hen. In commercial egg production, most eggs sold for consumption are unfertilized.
So the growing chick inside gets air to breathe.
The purpose of the yolk in a chicken egg is to feed the chick. It is a store house of nutrients and is rich in protein and fat.That is why the yolk is said to be the unhealthy part of the egg in terms of high cholesterol content for calorie and fat conscious people.
The yolk in an egg provides essential nutrients and fats for the developing embryo. It also acts as a source of energy for the growing chick.
An egg yolk is an undeveloped egg. If the egg is fertilised it would become a chick. The eggs we eat are the equivalent of a women's period (time of the month). Dark
The germinal disc. The egg is really just a single cell, until it is fertilized. The blastodisc (white spot on top of the yolk) is what will become part of the fetus when fertilized with sperm. Then the fetus feeds off the yolk to continue developing.
