Grade AA eggs are great for frying and poaching, and any other preparations in which appearance is important (like eggs benedict).
When an egg is first laid it is warm?
When an egg is first laid, it is warm. As it cools, the contents contract and the inner shell membrane separates from the outer shell membrane to form the air cell. The candler uses the size of the air cell as one basis for determining grade.

What are the 2 components of egg?
Structure and composition The structural components of the egg include the shell and shell membranes (10 percent); the albumen or white (60 percent), including the thick albumen, the outer thin albumen, the inner thin albumen, and the chalazae; and the yolk (30 percent).
Do eggs sink or float when they go bad?
If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air. An egg can sink and still be bad, while an egg that floats may still be fine to eat (3).
