An unfertilized chicken egg that is not collected and refrigerated will eventually start to decay. You can put the egg in a glass of water, if it sinks to the bottom then it is still fresh.
You can't, there's an ACTUALL baby chick in there.
Well, if you are talking about a normal chicken egg then yes you can. You can buy a fresh egg or you can get them from a supermarket/grocerie.
An egg can be fresh or several weeks old when you buy it. The best way to test for freshness is to put the eggs in a bowl of water. If the egg lays flat it is fresh, if it trys to stand on edge it is less fresh, but still okay. If it trys to float, do not use it.
The egg, 1st of all because there were eggs long before birds, but if you mean a chicken's egg then it is still the egg. This is because when a new species evolves, the egg is say, given birth to a sub-chicken, and the new species (chicken) is inside the egg, which is techically now a chicken's egg.
A fresh chicken egg will sink, an old egg will float. The egg has an air pocket in the blunt end that grows as the egg dries out.
Nothing, as long as it is not rotten, it is just like eating a chicken egg. A chicken is a bird.
It keeps it fresh long.
Make a chicken trap and trap a chicken but don't cook it. Then make a chicken coop and place it down somewhere. Interact with the chicken coop and it'll let you put the chicken on the chicken coop. Do that and then interact with the chicken on the coop. Serenade the chicken. Then after you serenade it, interact with it again. It will let you collect an egg. Ta-Da! You got yourself a nice, fresh egg.
Once you boil the eggs they are no longer fresh.
