Why is chicken called non vegetable?

Here's why:

* Chicken is an animal product. It's classified as meat, specifically poultry.

* Vegetables are plants. They are part of the plant kingdom.

* Animal products and plant products are distinct categories. They are not grouped together or considered the same.

It's likely you're thinking of the term "non-vegetarian" or "non-vegan," which are used to describe diets that include animal products.

To clarify:

* Vegetarian: A diet that excludes meat, poultry, and fish, but may include eggs and dairy products.

* Vegan: A diet that excludes all animal products, including meat, poultry, fish, eggs, dairy, and honey.

So, while "non-vegetable" isn't a common term, it's understandable why someone might use it to refer to a non-plant-based food.
