Marine Shell Grit for Chicks & Quail 20 kg | 1–2 mm Calcium Grit

Drobshell GRIT Crushed Marine Shell Grit for Poultry 1–2 mm (20 kg bag) is a 100% natural mineral feed supplement designed to replenish calcium and essential minerals in the diet of poultry. Suitable for laying hens, broilers, ducks, geese, turkeys, pheasants, quail and pigeons, this premium marine shell grit provides a natural source of highly available calcium to support healthy birds and improved egg production. The fine 1–2 mm particle size makes it ideal for baby chicks, young poultry and adult laying hens alike. In addition to supplying calcium, the shell grit promotes healthy digestion by helping grind feed in the gizzard, improving nutrient utilisation. If your flock is producing soft, cracked or misshapen eggs, Drobshell Marine Shell Grit is an effective way to improve eggshell strength and reduce egg breakage.

Benefits of Crushed Marine Shell Grit for Chickens

• 100% natural source of calcium and essential minerals – produced from specially processed marine shells.
• Stronger eggshells – the naturally occurring calcium helps laying hens produce hard, durable eggshells, reducing egg breakage.
• Improved laying performance – calcium and naturally occurring nutrients support egg production and enhance overall eggshell quality.
• Supports healthy bones and skeletal development – calcium is essential for bone formation and mineralisation, helping reduce bone weakness and brittleness.
• Promotes healthy digestion – shell grit assists the gizzard in mechanically grinding feed, improving digestion and nutrient absorption in poultry and pigeons.
• Economical large pack – supplied in a 20 kg bag, making it ideal for long-term use and larger flocks.

What Is Marine Shell Grit for Poultry?

Marine shell grit is a natural calcium supplement produced from cleaned and crushed marine shells sourced from the seafood industry. After thorough cleaning and processing, the shells are crushed into a uniform particle size, making them easy for chickens, pigeons, quail and ornamental birds to consume. Once ingested, the shell particles dissolve slowly in the digestive system, helping grind feed while providing a gradual release of calcium. Unlike crushed eggshells, which release calcium quickly, marine shell grit provides a longer-lasting source of calcium, making it a more effective supplement for laying poultry.

Drobshell Marine Shell Grit 1–2 mm for Chicks & Quail

This versatile natural mineral supplement is suitable for virtually every poultry flock. The fine 1–2 mm particle size makes it:

• Ideal for baby chicks and young pullets.
• Perfect for quail and small poultry species.
• Suitable for adult laying hens and all other backyard and farm poultry.

How Does Marine Shell Grit Benefit Poultry?

Unlike agricultural limestone, crushed marine shell grit with a 1–2 mm particle size dissolves more slowly in the digestive system. This gradual breakdown provides a sustained release of calcium, which is especially important overnight when laying hens form eggshells but are no longer eating feed. Calcium also supports healthy heart function, maintains electrolyte balance, and contributes to the proper functioning of the nervous and immune systems in poultry.

How to Recognise Calcium Deficiency in Chickens

Calcium deficiency in chickens can often be identified by soft-shelled eggs, thin or fragile eggshells, reduced egg quality, lethargy and mobility problems. Eggshells may become misshapen, rough or uneven and frequently crack immediately after laying, in the nest, or during egg collection. Egg eating (cannibalism) can also be a sign of insufficient calcium intake. Birds suffering from calcium deficiency may become weak, spend more time sitting, have difficulty walking and develop enlarged joints due to poor bone mineralisation.

How to Feed Marine Shell Grit to Poultry

Marine shell grit can be offered in two ways:

1. Free-choice feeding
   Provide the shell grit in a separate feeder or container. Birds will naturally regulate their calcium intake according to their individual nutritional requirements, especially during periods of intensive egg production.
2. Mixed with feed
   Recommended dosage: approximately 50 g of shell grit per 1 kg of feed.

For best results, offer marine shell grit during the afternoon or evening, as laying hens utilise calcium overnight when forming eggshells. If birds selectively avoid larger particles and you have access to a grain mill, the shells can be ground into a finer consistency and mixed directly with poultry feed.
