U.S Grade B eggs are usually used to make liquid, frozen, and dried egg products, as well as other egg-containing products. Generally you do not see Grade B eggs sold on the retail market as fresh eggs.
Eggs have a shell on it to stop it breaking
Eggs are graded Grade A, AA or B based on the quality of the shell, white and yolk and the size of the air cell within the egg. Grade "A" indicated an assurance of: Thick albumen (white) A round, well centered yolk A clean, uncracked shell with a "normal" egg shape. A small air cell within, less than 5mm.
the grades of eggs are like the rating of the eggs. Grade A eggs are the best grade B eggs are the second best grade C eggs are okay grade D eggs aren't very good and so on.
ROFL can you imagine eggs without a shell? They have a shell so that the chicken doesn't fall out a go boom!
Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
eggs
They do have Grade B eggs, they're just not as good (well formed) as Grade A eggs and so not sold in most supermarkets.
Grade A.
Reptile eggs have shell membranes.
The grading of eggs is done by "candling" in which a light is shown through the egg to determine the quality of the contents. If the yolk is unbroken and round then it is considered "A" grade and suitable for retail or home use. A grade of AA is given to fresh eggs with a strong shell that can be cooked, unbroken, and made into hard or soft boiled eggs. So, yes, AA is slightly better than a simple A.
in a shell
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.
