Fairy Eggs: 8 Reasons Why Chickens Lay Small Eggs
Inside: Discover why chickens lay small eggs, including fairy eggs, first eggs, stress, nutrition, hormones, and seasonal changes. Learn how to support egg production.
Egg production is a fascinating process, and chicken keepers often encounter surprises along the way. One such surprise is discovering a smaller-than-normal egg in the nesting box. These tiny eggs, sometimes called “fairy eggs,” can occur for several reasons. Whether you’re a new chicken owner or an experienced poultry farmer, understanding the causes behind why chickens lay small eggs can help you better manage your flock’s health and egg production.

Fairy Eggs: 8 Reasons Why Chickens Lay Small Eggs
Every once in a while we all get a fairy egg. In the long run, it doesn't affect your flock, or homestead unless you were really counting on that egg for breakfast.
Miniature eggs are just one of the many things that you'll find in the nesting box when you raise chickens. Yolkless eggs or double yolks eggs or maybe a tiny yolk, thinner shells or eggs lacking a shell altogether, or bigger eggs than you were expecting instead of little fart eggs. Personally, I would rather go out in the morning and find a tiny little egg instead of large eggs because then I am going to worry about a prolapsed hen.

What Are Fairy Eggs?
Fairy eggs, also referred to as wind eggs, rooster eggs, or witch eggs, are unusually small eggs a hen lays. Unlike normal eggs, fairy eggs sometimes lack yolks, though they can occasionally contain one. These eggs are typically a sign of an irregularity in the hen’s reproductive cycle rather than a serious health concern.
Possible Reasons for Small Eggs
There are multiple factors that can contribute to the production of small eggs. Below are some of the most common reasons why your chickens may be laying undersized eggs:
First Eggs from Young Hens
When a pullet (a young female chicken) starts laying eggs, her reproductive system is still maturing. The first eggs a pullet lays are often smaller than normal and may be a malformed egg or soft-shelled. This is entirely natural and usually resolves within a few weeks as her system regulates itself.
As she continues to lay, the eggs will gradually increase in size. A hen will lay her first egg at about 18 weeks of age, depending on the breed of chicken you have.
Stress or Environmental Factors
Stress plays a significant role in egg production. Your backyard flock may be experiencing stress from sudden environmental changes, such as extreme weather conditions, loud noises, predator threats, or changes in their flock dynamics, and may lay irregular eggs, including smaller ones.
Tips for minimizing stress:
- Ensure a stable and safe living environment.
- Provide consistent access to food and clean water.
- Minimize disturbances from predators or other animals.
Nutritional Deficiencies
Proper nutrition is crucial for healthy egg production. If a hen lacks essential nutrients like calcium, protein, or certain vitamins, her eggs may be smaller than normal, or lead to other health problems.
Tips for maintaining a well-balanced diet:
- Feed your flock high-quality layer feed.
- Supplement with oyster shells or crushed eggshells for calcium. A lack of calcium will also lead to weak shells or eggs without shells.
- Provide protein-rich treats like mealworms or black soldier fly larvae in moderation.
Hormonal Imbalances
Hens rely on a precise balance of hormones to regulate egg production. Any hormonal fluctuations, particularly in young hens just starting to lay or older hens nearing the end of their laying cycle, can result in the occasional small egg.
If a hen experiences an interruption in her hormone production, she may lay smaller eggs or even produce fairy eggs without yolks.
Underdeveloped or Aging Oviduct
The oviduct is responsible for forming the egg as it moves through the hen’s reproductive system. In young hens, the oviduct may not be fully developed, leading to smaller eggs.
In older hens, the oviduct may not function as efficiently as it once did, causing irregularities in egg size and shell quality.
Parasites or Illness
Internal parasites, such as worms, and diseases affecting the reproductive system can impact a hen’s ability to lay normal-sized eggs.
Infected hens may experience nutritional deficiencies, weight loss, or decreased egg production overall. If you suspect parasites or illness, consulting a veterinarian and implementing a regular deworming and health check routine is recommended.
Molting and Seasonal Changes
Chickens go through a molting phase where they shed and regrow feathers, often leading to a temporary drop in egg production. During this time, hens may lay smaller eggs due to energy being redirected towards feather regrowth. Similarly, shorter daylight hours in winter can affect hormone levels, causing temporary irregularities in egg size.
Breed Differences and Genetics
Some chicken breeds naturally lay smaller eggs than others. While this article focuses on unexpected small eggs rather than specific breeds, it’s worth noting that bantam chickens, a smaller breed, for example, lay smaller eggs as part of their genetic makeup.
Additionally, some hens may simply have genetic predispositions to laying smaller eggs, even if they belong to a breed known for large eggs.
What to Do If Your Chicken Is Laying Small Eggs
If you notice occasional small eggs, especially from young or aging hens, there’s generally no cause for concern. However, if a previously consistent layer suddenly starts laying smaller eggs frequently, consider the following steps:
- Evaluate Diet: Ensure they receive a well-balanced layer feed with adequate calcium and protein, sometimes a grower feed can give them a protein boost if they need it.
- Check for Stressors: Reduce any environmental stressors that could be affecting your hens. Make sure the chicken coop is clean and safe for example, that they have enough space for the number of birds you have. Chickens need at least 3–5 square feet of space per chicken inside a coop, and 8–10 square feet of outdoor space per chicken.
- Monitor Health: Watch for any sign of illness, parasites, or unusual behavior in your flock. A dust bath can help with parasites, they should always have one accessible. Make sure that they meet the standard body weight for a healthy hen of their breed.
- Observe Egg Production Trends: Track your flock’s egg-laying patterns to detect any persistent issues.
Small eggs, including fairy eggs, are a natural occurrence in egg production and are often temporary. Young pullets, stressed hens, nutritional imbalances, hormonal shifts, and seasonal changes can all contribute to the occasional small egg. By ensuring a stable, healthy environment with proper nutrition and care, you can support your flock’s overall egg production and well-being.
If you continue to notice irregularities or suspect underlying health concerns, consulting a poultry expert or veterinarian can provide additional guidance. Whether large or small, each egg is a fascinating part of a hen’s reproductive journey, and understanding the reasons behind variations can enhance your chicken-keeping experience.
