Please don't move her. It will stress her and she may not return to take care of her babies. If you absolutely have to use the vehicle then carefully placing nest into a strong hanging plant pot and hanging close by vehicle where she can see babies then that will help her greatly. Please ensure you use a glove to move nest to avoid human scent. Thank you for caring and allowing her to take care of her young. She chose your home to have her family and that is such an immense privilege. ❤
