OYTA Oyster Shell Grit is a premium, large grade (4-7mm) soluble calcium-rich grit specially designed for breeding and laying birds. Providing an essential source of calcium, this grit supports strong eggshell formation, healthy bone development, and overall bird vitality.
Unlike insoluble flint grit, oyster shell grit dissolves gradually within the bird’s digestive system, delivering a steady supply of calcium exactly when it is needed most.
Why Choose OYTA Oyster Shell Grit?
High in Natural Calcium – Essential for strong eggshell production.
Large 4-7mm – Suitable for most poultry and breeding birds.
Slow Solubility – Provides a consistent calcium release.
Supports Bone Strength – Promotes skeletal health in laying birds.
Helps Prevent Soft-Shelled Eggs – Maintains eggshell quality during peak lay.

Produce strong, well-formed eggshells
Maintain bone density
Support long-term laying performance
Suitable For
