Therefore, it is perfectly fine and natural for your new bunny to eat grass. There is no reason to be concerned as long as the grass is not treated with pesticides or other harmful chemicals.
However, make sure the grass your rabbit is eating is safe and uncontaminated. Avoid areas with heavy traffic, such as roadsides, or areas where pesticides or fertilizers have been used.
In addition, monitor your bunny's grass consumption. While grass is an essential part of their diet, it should not make up the entire meal. A balanced diet for rabbits includes a variety of foods, including hay, fresh vegetables, and limited amounts of fruit.
