Mixed Grit for Chickens

Why do chickens need grit?

Chickens don't have teeth, so they cannot chew their food. Grit remains in the gizzard (a muscular stomach organ) and acts like millstones to mechanically grind food into digestible particles. Without adequate grit, chickens cannot properly digest their feed, leading to poor nutrition and health issues.

What's the difference between oyster shell and grit?

Oyster shell is soluble calcium that gradually dissolves in the digestive system, providing essential calcium for eggshell formation and bone health. Flint grit is insoluble and remains in the gizzard permanently to grind food. Chickens need both - this product conveniently provides both in one mix.

How much should I provide?

Offer free-choice access at all times in a separate feeder or dish. Chickens will naturally regulate their intake based on individual needs. A small flock of 4-6 birds typically consumes approximately 1.5kg every 2-3 months, though consumption varies with diet and laying activity.

Should grit be separate from their feed?

Yes, always offer grit in a separate feeder or sturdy dish rather than mixing it into feed. This allows chickens to self-regulate their intake according to individual needs, particularly important as calcium requirements vary significantly between laying and non-laying birds.

Do free-range chickens still need grit?

Yes! Whilst free-range chickens may find some natural grit sources, they cannot consistently access sufficient quantities of both calcium and appropriate-sized flint grit. Always provide supplemental mixed grit to ensure adequate intake.

My chickens aren't eating the grit. Should I worry?

Chickens eating primarily pellets or mash may consume less grit than those eating whole grains or kitchen scraps. However, laying hens should regularly consume oyster shell for calcium. If hens completely ignore it and you're experiencing soft eggs, consult a veterinarian as this may indicate a health issue.

Can I give this to chicks?

Chicks under 8 weeks eating starter crumble generally don't require grit unless you're offering treats or whole grains. After 8 weeks or when introducing treats, provide appropriately-sized chick grit. This mixed grit is formulated for adult chickens.

Will too much grit harm my chickens?

Chickens naturally self-regulate grit intake and rarely overconsume. The gizzard can only hold a certain amount, and excess simply passes through. Free-choice availability is safe and recommended.

Why are my eggs soft or thin-shelled?

Soft or thin shells typically indicate calcium deficiency. Ensure hens have constant access to oyster shell, check that the grit is fresh and dry (moisture reduces palatability), and verify they're eating it. Persistent issues may indicate health problems requiring veterinary attention.

How should I store mixed grit?

Keep in a cool, dry place with the pouch resealed after use. Moisture can cause oyster shell to clump and reduces palatability. Properly stored grit remains effective indefinitely.

What if my chickens only eat one type and ignore the other?

This is normal! Individual birds have different needs. Active layers consume more oyster shell, whilst birds eating whole grains take more flint grit. The mixed format allows each bird to select what they need.

Can ducks use this mixed grit?

Yes, ducks also require grit for digestion and calcium for egg production. However, ducks may prefer slightly different grit sizes. This product works well for most waterfowl alongside chickens.

My chickens eat whole grain scratch. Do they need extra grit?

Absolutely! Whole grains are harder to digest than pellets or mash, making grit essential. Chickens eating scratch, kitchen scraps, or foraged materials have higher grit requirements than those on processed feeds only.

Is this organic?

Oyster shell and flint grit are naturally-occurring minerals. Whilst not certified organic, they are natural, unprocessed materials suitable for organic poultry keeping.
