Why Do Hens Eat Broken Eggs?

It's a common sight in many chicken farms or backyards: hens pecking at broken eggs. This behavior raises questions among many poultry enthusiasts and pet owners. Why do hens eat their own eggs, and is there a deeper reason behind this habit?

Calcium Deficiency and Nest Protection

One of the primary reasons hens eat broken eggs is to replenish the calcium that is lost during the egg-laying process. Breaking an egg causes calcium to be lost, as some of the egg's content spills out. Hens instinctively consume these broken eggs to counterbalance the calcium deficit they experience.

Another reason is to protect their nests from predators. By eating broken eggs, hens can hide the location of their nest, which might otherwise attract unwanted attention from predators. Regularly eating broken eggs helps maintain the secrecy of their breeding site, ensuring the safety and security of their eggs.

Environmental Factors Counting Towards Perfect Hens

However, dietary and environmental factors also play a significant role in a hen's egg-eating habits. Let's explore a few other reasons hens might consume their broken eggs:

Lack of Sufficient Fresh Food, Clean Water, and Space

When hens are not provided with adequate fresh food, clean water, and space to roam, they are more prone to developing this behavior. Well-fed hens that have access to a variety of foods, including bugs, seeds, and greens, are less likely to engage in egg-eating. These hens are generally too busy foraging and enjoying their environment to exhibit such behavior. It’s important to note that lack of proper nutrition and space can lead to stress and imbalance, which may manifest in unusual behaviors like egg-eating.

Ensuring Egg Quality

Additionally, hens eating broken eggs in the incubation period help ensure that only intact eggs are incubated. By consuming broken eggs, hens maintain the integrity of their nest and the environment in which the remaining eggs will hatch. This ensures that the eggs remaining in the nest have a higher chance of hatching without contamination.

Nutritional Benefits and Curiosity

Eggs are extremely nutritious, and chickens know this. Even a broken egg is a valuable source of nutrition. By eating their own broken eggs, hens can effectively recover the nutrients they have already expended during the egg-laying process. This behavior is a survival instinct deeply rooted in their biology.

It's also worth noting that chickens are not strictly vegetarians. They are omnivores and have a natural inclination to eat a variety of foods, including bugs, worms, and even other chickens if the opportunity arises. This behavior is a reflection of their natural instincts and dietary needs.

So, while hens eat broken eggs for a combination of biological and instinctual reasons, it is important for chicken owners to ensure that their hens have a balanced diet and adequate living conditions. By doing so, they can prevent such behavior and promote a healthier and happier flock.
