Do chicken lay the same size egg all time?

Here's why:

* Age: Younger hens lay smaller eggs than older hens.

* Breed: Different breeds of chickens lay eggs of different sizes. Some breeds are known for laying large eggs, while others lay smaller eggs.

* Diet: A hen's diet plays a role in egg size. A hen with a balanced and nutritious diet will lay larger eggs than a hen with a poor diet.

* Season: Egg size can vary slightly depending on the season. Hens tend to lay larger eggs in the spring and summer when they have more access to fresh food and sunlight.

* Stress: Stressful conditions can affect egg size. A hen that is stressed or overcrowded may lay smaller eggs.

* Individual Variation: Just like people, hens have individual variations. Some hens consistently lay larger eggs than others, even within the same breed and under the same conditions.

So, while there might be some general trends, egg size is influenced by a number of factors and can vary significantly from hen to hen and even within the same hen's egg production.
