Finding a soft, squishy, or completely shell-less egg in your nesting box can be alarming, as these fragile oddities lack the hard outer shell (calcium carbonate) that protects the yolk and egg white.

If you just found one of these in your coop, don’t panic. While it can look bizarre, a soft-shelled egg is basically your flock’s way of sending you a distress signal. It is usually the result of a temporary imbalance, but if ignored, it can lead to serious health issues for your hens, such as egg binding.

Top 5 Reasons Your Chickens Lay Soft Shelled Eggs

1. Calcium Deficiency Is the Main Cause

Eggshells are about 95 percent calcium carbonate. Hens need a constant supply to produce eggs daily.
If calcium intake is too low, the body pulls it from bones. Once reserves drop, eggs become thin or soft.

2. Poor Calcium Phosphorus Balance

Calcium alone is not enough. It needs support from phosphorus and vitamin D3.

• Vitamin D3 helps absorb calcium
• Phosphorus helps form strong shells

Too much phosphorus from treats like mealworms blocks calcium absorption. This leads to weak shells even if calcium is available.

3. Heat Stress Affects Shell Formation

High temperatures can disrupt egg production.

Chickens cool down by panting, which changes blood chemistry. This reduces key compounds needed for shell formation, resulting in softer eggs.

4. Age Plays a Big Role

Shell quality varies with age.

• Young hens may lay soft eggs as their system develops
• Older hens absorb calcium less efficiently

Both stages can lead to weaker shells.

5. Too Many Treats Reduce Nutrition

Excess treats dilute a balanced diet.

If treats exceed 10 percent of daily intake, hens get less protein and calcium. This quickly leads to poor shell quality and lower egg production.

How to Fix Soft Shelled Eggs

• Provide a calcium rich diet such as SupremeGrubs' Black Soldier Fly Larvae
• Maintain proper nutrient balance
• Reduce treats
• Keep hens cool
• Adjust care based on age

These steps help restore strong and healthy eggshells.

As more chicken keepers look for better ways to care for their flocks and reduce waste, black soldier fly larvae are becoming a smarter choice. They are nutrient rich, naturally high in calcium, and far more sustainable than many traditional treats.

At SupremeGrubs, we believe treats should do more than just entertain your flock. They should support health, fit into a more responsible food system, and help backyard keepers make better everyday choices.

A more sustainable way to feed your flock

Traditional protein sources can require large amounts of land, water, and energy. Black soldier fly larvae offer a more efficient alternative because they can be raised with fewer resources and as part of a circular system that helps turn organic byproducts into useful nutrition.

That makes them one of the most promising options for sustainable animal feeding today.

Why black soldier fly larvae are better than mealworms

Many chicken owners start with mealworms, but black soldier fly larvae offer a more functional nutritional profile.

They are especially valued for their naturally high calcium content, which helps support laying hens and strong eggshell production. They also provide quality protein and beneficial fats, making them a nutrient dense treat your flock can actually benefit from.

For keepers looking for a mealworm alternative for chickens, black soldier fly larvae are a clear upgrade.

More than a treat

Black soldier fly larvae contain more than just protein. They also provide naturally occurring compounds like lauric acid and chitin, which are linked to gut health and overall wellness.

That means they are not only a sustainable chicken treat. They are also a practical way to support your flock’s daily nutrition.

Why SupremeGrubs

SupremeGrubs makes it easy to choose a cleaner, smarter treat for your birds. Our black soldier fly larvae are raised with quality in mind, giving chicken keepers a high calcium, eco friendly option that aligns with both flock care and sustainability.
