How much is okay?
Do not free-feed shell pieces. If used at all, they must be baked clean and powdered fine.
Rule of thumb: treats of all kinds should stay under ~10% of daily calories.
How to prepare them
- Only consider clean, baked, finely powdered shell.
- Never offer large sharp shards.
- Ask your vet before adding calcium extras.
Risks & exceptions
- Sharp shell pieces can injure mouth or gut.
- Extra calcium is not automatically helpful.
- Raw shell can carry bacteria.
Egg shells are a vet-guided optional powder at most — not a crunchy snack.
If they ate too many
A larger portion or the wrong preparation is most likely to cause trouble.
- Mouth irritation from shards
Call your vet / pet poison line if:
- Swallowing large sharp pieces
