Yes. In Jainism, the core principle is ahimsa (non-violence). Jains generally follow a strict vegetarian diet and do not eat meat, including chicken. Eggs are also typically avoided by many Jains, though practices can vary slightly by community. The overall aim is to avoid harming any living being.

If you’d like, I can point you to a JainKnowledge page that discusses Jain dietary rules in more detail.
