Shiluach Haken: Again and Again?

Hi, Can a person do the mitzvah of shiluach hakein (sending away the mother bird) on the same nest more than one time? For instance, I did the mitzvah on the nest already but there was only one egg in the nest. Now it’s been 12 days and the mother bird is still sitting in the nest and there are 3 eggs there. Can I do the mitzvah again since it’s been a few days and there are more eggs, or will doing it twice be considered cruel to the mother bird? Thank you
