Why Do Chickens Eat Their Eggs?

The answer to why chickens eat their eggs can be many reasons. Chickens will consume their own eggs because of their nutritional value of eggs, especially calcium. Some chickens eat eggs to provide them with food during the day, while others eat eggs to provide them with warmth during winter.

Below are the most common reasons why your chickens may be eating their own eggs.

6 Reasons Why Chickens Eat Their Own Eggs

 Reason #1 – Overcrowding

Overcrowding is a common problem in overcrowded areas, and it can lead to egg-laying problems. When too many chickens are in one area, they start to lay eggs at an increased rate. This results in less food for the rest of the flock, and eventually, the flock becomes overpopulated and unable to lay eggs. This can lead to serious problems and could cause the hen to start eating the eggs.

Reason #2 – Not Enough Nesting Boxes 

If you don’t have enough nest boxes, your chickens will not be able to lay eggs. Nest boxes are important for two primary reasons. First, they help to protect your chicks from predators and other animals. Second, they help to ensure that your eggs are fertile and will hatch into healthy chickens. Without enough nest boxes, your chickens may start to eat the eggs.

Reason #3 – Calcium Deficiency

Chickens eat their own eggs because they aren’t getting enough calcium. The eggshell is made up of calcium, which can deplete the hen’s calcium content.

When the chicken needs more calcium in their body, they will be tempted to eat the eggs due to the calcium. Chickens have to eat to lay their eggs and they can’t do that if they’re not getting the right nutrients.

Reason #4 – Boredom

When chickens have nothing else to do, they may start eating their own eggs. This is because chickens are omnivores, which means that they will eat both plants and animals. When they have no other food source, chickens may start eating their own eggs or even the baby chicks inside the eggs. This is not just a problem for chicken owners – it’s also a problem for chicken farmers who want to produce more eggs!

Reason #5 – Chickens Use Eggs As A Source Of Energy And Protein

Eggs provide a source of energy and protein that chickens need in order to maintain their body temperature. At the end of the day, if the chicken is not getting enough nutrients from their food, they will turn to eat their own eggs.

For hens, egg production is essential for survival because birds use them as a source of energy and protein.

Why Do Chickens Eat Their Eggshells?

The most obvious answer is that this behavior helps chickens to keep their body temperature regulated. When they eat the eggshells, they excrete the calcium into their droppings which helps them to keep their body warm. It also gives them a source of protein and energy that they need in order to maintain their body temperatures during times of low food supply.

In addition to this, eggshells have plenty of calcium content. The hen knows this and will each the eggshells when they feel they are not getting enough calcium in their diet.

How To Prevent Chickens From Eating Their Own Eggs

One way to prevent chickens from eating their own eggs is to make sure they have enough food in their coop. Chickens need a constant supply of food, and if they don’t have enough food, they will start eating their own eggs.

Another way to prevent chickens from eating their own eggs is by giving them plenty of water. Chickens need water for hydration and for digestion. If you give your chickens plenty of water, it will keep them satisfied without the temptation of eating their eggs.


Chickens eat their eggs for many different reasons. It’s important to find out the reason, especially if you’re planning to collect the eggs.
