Quantity / label reference
No verified spoon dose or universal grams per kg. Calculate calcium against the whole ration and other calcium sources.
Calcium sources and insoluble grit have different jobs

- 01
Identify the material
Read the composition. A fine particle size alone does not establish whether a grit mixture is soluble or insoluble.
- 02
Separate the roles
Finches hull their seeds and do not need insoluble grit to grind seed. Soluble calcium has a nutritional role that must be considered separately.
- 03
Review the ration
Check existing calcium and vitamin D3 from food and other products. Do not turn a free-choice mineral product into an invented measured supplement dose.
The bowls illustrate different materials, not a recommendation to offer every material together or without limit.
- What it provides
- Home-prepared eggshell is a calcium ingredient, not a complete mineral supplement or insoluble grit.
- When to consider it
- Prefer a traceable bird-grade calcium product when preparation and calcium inclusion cannot be validated. Unmeasured shell powder is not a dosing method.
- Intended birds / scope
- Granivorous ornamental birds; species and life stage determine how it fits the whole ration.
- How it is given
- In a clean feeding dish; oral feeding by the birds.
- Frequency / duration
- No routine frequency established for the unidentified pack; first obtain a documented inclusion plan.
- Preparation
- No validated home heat-treatment protocol is supplied here. Record a proven food-hygiene process, final particle size and measured inclusion before use.
- Combining products
- Do not combine several unmeasured additions. Record grams per kg of final food and account for the base feed’s existing nutrients.
- Storage & handling
- Keep sealed, cool and dry, away from pests. Use a dry scoop, retain batch/expiry, and reject damp, mouldy or rancid material.
- Breeder tips
- Mineral availability does not establish adequate calcium or vitamin D. Match the exact product and avoid duplicating several calcium sources blindly.

Use & compatibility notes
Record preparation and amounts. Review total calcium sources with the full ration rather than adding several products independently.
