Product description
Oyster shells 25 Kg are broken oyster shell and therefore a natural source of calcium. That calcium is needed for strong bones, a healthy beak and, in breeding birds, for eggshells that do not stay too thin.
The shells also help a little with grinding food, but that is their second role: where grit is hard and does not dissolve, oyster shell mainly releases calcium.
Offer them separately in a feeding dish or mix them through the food. Suitable for budgies, canaries, finches and also for chickens.
Advantages
Calcium from a natural source
Broken shell, nothing added. Your birds take what they need.
Important for the eggshell
Laying birds use a lot of calcium, and a shortage shows in thin or soft shells.
Also for bones and beak
Not only during breeding: calcium is needed all year round.
Frequently asked questions
What are oyster shells for?
As a source of calcium. It supports bones, the beak and the forming of strong eggshells in laying birds.
Which animals are they suitable for?
For budgies, canaries, finches and other cage and aviary birds, and also for chickens.
How do I offer them?
Separately in a feeding dish or mixed through the food. Make sure there is always some available, especially in the breeding season.
How much should I give?
No need to measure. Keep some in a separate dish at all times and refresh regularly so it stays clean; your birds take what they need.
What is the difference with grit?
Grit, such as Bird grit 25 kg, is hard and stays in the gizzard to grind seed. Oyster shells dissolve and provide calcium. They do not replace each other, so many breeders offer both.
