Chicken egg is the usual food on our table. Shelves of shops are full of a huge selection of this product. And it differs not only by manufacturer and price, but also by weight category, which basically forms the price. It is useful to know what this category is and what it depends on.
Egg Labeling Value
By our standards, any egg produced by a poultry farm has its own marking. The marking consists of two elements: letters and numbers. The letter is responsible for the type of product, and the number or letter for the size (weight). There are two types of letter designations:
- “D” - diet, a week is allocated for its implementation;
- “C” - a canteen, must be realized in 25 days.
Important! Imported slightly different labeling: S - Small (up to 53 g), M - Medium (53–63 g), L - Large (63–73 g), XL - Very Large (over 73 g).
By weight, they are divided into the following categories:
- 3 - the third category, the smallest;
- 2 - second;
- 1 - first;
- O - perfect;
- B is the highest.
Average weight of a chicken egg
Each described variety corresponds to a certain value of the product in grams.
| Category | Minimum weight, g | Average weight, g |
| 3 | 35 | 40 |
| 2 | 45 | 50 |
| 1 | 55 | 60 |
| O (select) | 65 | 70 |
| the highest | 75 | 80 |
| two-yolk | 80 | - |
Unshelled raw egg
When athletes calculate their daily diet, it also matters to them how much an egg weighs without a shell. To determine the weight of the contents of the product, you need to know what percentage of the total weight of the shell is. It accounts for approximately 12%. Based on the above data, you can get the following:
| Category | Shell, g | Unshell, g |
| 3 | 5 | 35 |
| 2 | 6 | 44 |
| 1 | 7 | 53 |
| 0 | 8 | 62 |
| the highest | 10 | 70 |
The mass of yolk and protein
In each category, the mass of protein and yolk is different, but on average the proportion of protein is 57%, and the yolk is 37%. In more detail, this ratio looks like this:
| Category | Yolk, g | Squirrel, g |
| 3 | 12 | 23 |
| 2 | 16 | 29 |
| 1 | 19 | 34 |
| 0 | 22 | 40 |
| the highest | 25 | 46 |
Boiled
It is important for supporters of diets and hostesses to know whether the mass of the raw product differs from the cooked one. To understand this issue, you need to go a little deeper into the anatomy of the egg. Its shell is permeable to air, but it releases it much more slowly than it lets in. Therefore, when cooking, no losses occur. When we remove the shell, the weight of the cooked contents will be equal to the weight of the raw contents of the shell.
Important! It is necessary to take into account the fact that if a product is stored for a long time, its contents nevertheless gradually evaporate, and when you cook it, it may turn out that its mass will not correspond to that declared by the manufacturer.
Egg weight by breed
Regardless of which direction a chicken from a particular breed belongs to, they all have the ability to rush. True, the size of the demolished product will vary. Most often, meat and egg chickens are demolished larger, and egg chickens are small. To receive goods of the highest category, selected laying hens are bred, which are fed according to a special scheme.
The average weight values for the most common breeds look like this:
| Breed | Egg weight |
| Rhode Island | 56–58 g |
| New hampshire | 58–59 g |
| Plymouth Rock | 56–60 g |
| Moscow | 56–58 g |
| Australorp | 60–62 g |
| Orpington | 60–61 g |
| Sussex | 56–58 g |
| May Day | 58–63 g |
| Livenskaya | 55–60 g |
| Yurlovskaya | 65–70 g |

Did you know? In 1956, a Leghorn chicken Blanchise chicken laid an egg that had a double shell and two yolks. Mass of this «miracles» amounted to 454 grams.
Thus, knowing the dependence of weight on various factors, you can determine which product is most profitable to purchase.
