In Jainism, eggs are not acceptable to eat — whether fertilized or unfertilized.

Reason in simple terms:

1. Ahimsa (non‑violence):

- Jain food rules avoid anything that is directly from an animal’s body in a way that involves killing or destroying potential life. - An egg is treated as life or potential life. Even if people call it “unfertilized”, from a Jain-dharma point of view it is still in the category of animal-origin food and against ahimsa.

1. Potential for life (praṇi‑bhav):

- Jain thinkers see eggs as belonging to a life-stream of beings (even when we can’t see a chick). Destroying or consuming that is seen as himsa (violence).

1. Purity of diet (sāttvik / “Jain veg”):

- A Jain diet is lacto‑vegetarian (plant foods + dairy with as little cruelty as possible). - Eggs (of any type: hen, duck, fish eggs like caviar, etc.) are outside this definition. They are treated like non‑veg, not like vegetarian food. ( jainknowledge.com)

1. Both main traditions agree:

- Digambar and Shvetambar traditions both teach that Jains should not eat eggs. - There may be small differences in household practice, but the ideal Jain conduct is clearly egg‑free. ( jainknowledge.com)

So, from a Jain dharma point of view: Unfertilized eggs are also not okay to eat. They are considered non‑Jain food, just like any other egg.
