Why do chicken eggs vary in size?

Egg size is related to the age of the hen — as a hen gets older, she lays larger eggs. Eggs are sorted at the grading station based on weight, not circumference, and packaged accordingly into the following sizes: pee wee, small, medium, large, extra large or jumbo. Learn more.

Why are my chicken eggs getting smaller?

Stress. Predators, weather extremes, not enough water or feed and disease or illness can all cause a hen to temporarily lay smaller than expected eggs. Until the stressor is corrected or eliminated, most hens will continue to lay small eggs or possibly no eggs at all.

What causes huge chicken eggs?

The egg size a hen lays has to do with the size of the shell gland and ratio of the length of the magnum (where the albumen is deposited) to the whole length of the oviduct. They grow larger as her system gets into the swing, and sometimes eggs don’t reach their full size until after the first molt.

How do you make chicken eggs bigger?

at the start of egg production will increase both hen weight and egg size. Protein level in the feed can be used to alter egg size at different stages of production. In the first couple of months of egg production feeding a high, 18\% to 20\% protein layer ration will increase egg size.

Why is my egg shell bumpy?

As a hen ages, the whites (or albumen) in their eggs naturally gets thinner, and since it’s more difficult for the shell to encase a watery substance, the shell can end up with bumps and ridges. Heat stress can also cause a wrinkled egg surface, as can poor overall nutrition, or a defective shell gland.

How do chickens increase their egg size?

Do chickens lay different sized eggs?

Chickens lay different-sized eggs for a variety of reasons, like breed, diet, or light exposure, but the primary factor is age. The USDA classifies egg size by the total weight of a dozen eggs, which is why some eggs in the carton may look slightly larger or smaller than the rest.
