Best Calcium Supplements For Laying Hens Australia
Calcium is one of the most important nutrients for laying hens. Every egg requires a significant amount of calcium to produce a strong shell, and hens that do not receive enough calcium may lay thin-shelled, soft-shelled or misshapen eggs.
Backyard chicken owners often provide additional calcium support during periods of peak egg production to help maintain normal eggshell formation and overall flock health. Products such as Vetsense Avi-CALCIUM 500mL offer a convenient liquid calcium supplement when used according to the manufacturer's directions.
This guide explains why calcium is important, signs that hens may not be receiving enough calcium, factors that affect eggshell quality and how calcium, vitamins, electrolytes and good flock management all work together to support healthy egg production.
Why Do Laying Hens Need Calcium?
Every eggshell is made primarily from calcium. Laying hens require adequate dietary calcium to produce strong shells while also maintaining their own bone health.
If hens do not consume enough calcium through their diet, their bodies may draw calcium from their bones to continue producing eggs. Over time this can affect both shell quality and the hen's overall condition.

Signs Of Calcium Deficiency In Chickens
Several factors can influence eggshell quality, but insufficient calcium intake is one possible cause.
Possible signs include:
- Thin eggshells
- Soft-shelled eggs
- Rough or uneven shells
- Broken eggs in the nest
- Reduced laying performance
- Poor shell strength
These signs are not always caused by calcium deficiency alone. Age, nutrition, disease, stress and environmental conditions may also contribute.
What Causes Thin Eggshells?
Thin eggshells are not always caused by a lack of calcium. Several factors may contribute to poor shell quality.
Common causes include:
- Older laying hens.
- Heat stress during hot Australian summers.
- Poor overall nutrition.
- Reduced feed intake.
- Insufficient Vitamin D.
- Illness or disease.
- General stress.
If shell quality suddenly declines across your flock, consider reviewing nutrition, water availability, parasite management and overall flock health.
Vetsense Avi-CALCIUM For Laying Hens
Vetsense Avi-CALCIUM 500mL is a liquid calcium supplement designed for poultry and birds according to the manufacturer's directions.
Many backyard chicken owners use Avi-CALCIUM during periods of laying to help support normal eggshell formation. Many also combine it with Vetsense Avi-VITAL Bird & Poultry Vitamins 500mL for nutritional support and Vetsense Avi-LYTE Electrolytes For Poultry 500mL during periods of heat stress.
Calcium During Peak Egg Production
Hens producing eggs regularly have increased calcium requirements. Supporting laying hens with quality nutrition, clean drinking water and appropriate calcium supplementation helps maintain normal shell formation throughout the laying season.
Good flock management should always include:
- Quality layer feed.
- Fresh clean drinking water.
- Routine parasite management.
- Clean nesting areas.
- Low stress.
- Appropriate calcium support.
Providing clean nesting boxes can also help reduce broken eggs and improve egg quality. Browse our Rollaway Nest Boxes Australia collection.
Calcium Vs Grit
Although both are important, calcium supplements and grit perform completely different roles.
| Supplement | Main Purpose |
| Calcium | Supports normal eggshell formation. |
| Insoluble Grit | Helps grind feed inside the gizzard for digestion. |
While calcium supports laying hens, grit assists digestion. Most backyard flocks benefit from appropriate access to both as part of a complete feeding program.
