Perrin Madox Fossilised Oyster Shell Grit 2–4 mm: Mineral Supplement for Poultry and Pigeons
Perrin Madox Fossilised Oyster Shell Grit is a mineral feed supplement made from crushed fossilised oyster shells.
Available in 2–4 mm grey granules, it is intended for pigeons, chickens, ducks, laying hens and other birds.
Naturally containing calcium carbonate, oyster shells provide a supplementary source of calcium, particularly useful during egg production.
A Natural Calcium Source for Birds
Calcium is an essential mineral in poultry nutrition.
It contributes to:
-
Eggshell formation in laying birds.
-
Bone development and maintenance.
-
Normal muscle function.
-
Maintaining the mineral balance of the daily feed ration.
Crushed oyster shells can complement a balanced diet adapted to the species and physiological needs of the birds.
A 2–4 mm Particle Size
The 2–4 mm granules are suitable for poultry and pigeons.
Compared with finely ground calcium sources, coarser shell particles can remain in the digestive tract for longer, allowing calcium to become available progressively.
This makes crushed oyster shells particularly useful for laying hens, whose calcium requirements increase during eggshell formation.
For Pigeons, Poultry and Other Birds
Perrin Madox Fossilised Oyster Shell Grit is intended for:
-
Pigeons.
-
Chickens.
-
Laying hens.
-
Ducks.
-
Other birds, according to their nutritional requirements.
It can be offered as part of a balanced feeding programme.
Directions for Use
Provide crushed oyster shells in a separate feeder or incorporate them into the daily feed ration, according to the nutritional requirements of the birds.
Adjust supplementation to take account of the calcium already present in the regular feed.
Always ensure access to fresh, clean drinking water.
