1, the weight of eggs will be affected by many factors such as egg size, variety and freshness. The size of an egg is one of the important factors affecting its weight. Generally speaking, larger eggs are heavier, while smaller eggs are lighter. This is mainly because the size of eggs is related to the nutrients they absorb in the production process and the individual differences of hens.
2. The kind of eggs will also affect their weight. The eggs of different breeds of chickens are different in size and shape, so their weight will be different. For example, the eggs laid by native chickens are usually smaller and lighter than those laid by commercially farmed chickens.
The freshness of eggs will also affect their weight. Fresh eggs are relatively heavy because of their high moisture content. Eggs will gradually evaporate when stored for a long time, so their weight is relatively light.
