What is the estimated mass of a chicken egg?

The estimated mass of a chicken egg is 50-70 grams.

However, this is just an average. The actual weight can vary significantly depending on factors like:

* Breed of chicken: Some breeds lay larger eggs than others.

* Age of hen: Older hens tend to lay smaller eggs.

* Diet: A hen's diet can affect egg size.

* Season: Eggs tend to be smaller in the winter and larger in the summer.

So, while 50-70 grams is a good general estimate, you should always check the specific weight of your eggs.
