Birds may eat their eggs due to stress, nutritional deficiencies, perceived threats, or to eliminate weak or non-viable eggs for survival of the brood.
Discovering that your birds have eaten their own eggs can be alarming. This behavior, while disturbing to witness, has several biological and environmental causes. From nutritional deficiencies to instinctive survival tactics, birds may consume their eggs for reasons that aren’t immediately obvious to human observers.
Primary Reasons Birds Eat Their Eggs
Nutritional Deficiencies
Birds require substantial nutrients for egg production. When lacking protein or calcium, they may eat eggs to replenish these vital resources. This is particularly common in:
- Young breeding pairs
- Birds fed seed-only diets
- Overbred females
For optimal nutrition, consider high-quality bird food that meets all dietary requirements.
Instinctive Behavior
Wild birds may eat eggs to:
- Hide evidence from predators
- Remove non-viable eggs
- Recycle nutrients
According to BirdForum discussions, this behavior is more common in captivity than in wild populations.
Species-Specific Egg Eating Habits
| Bird Type | Likelihood | Common Triggers |
|---|---|---|
| Parakeets | High | Young age, poor nesting setup |
| Chickens | Moderate | Calcium deficiency, boredom |
| Corvids | Low | Captivity stress |
Age-Related Factors
Young birds often lack proper parenting instincts. As noted by LaFeber’s avian experts, parakeets under two years frequently destroy eggs accidentally or intentionally.
Preventing Egg Eating in Captive Birds
Dietary Solutions
Provide:
- Commercial egg food
- Crushed oyster shell
- Fresh vegetables
- High-protein pellets
Environmental Adjustments
Proper housing is crucial. Consider appropriate cages and:
- Correct nest box placement
- Sufficient space
- Privacy for breeding pairs
Nest Box Specifications
Ideal nest boxes should:
- Be mounted high in the cage
- Have proper dimensions for the species
- Include clean nesting material
When to Stop Breeding Attempts
Persistent egg eating often indicates:
- Chronic nutritional issues
- Genetic predisposition
- Psychological factors
In these cases, permanent separation or retirement from breeding may be necessary. Monitor your birds closely and consult an avian veterinarian if the behavior continues despite interventions.
