I would watch the bigger female very carefully. Even though she is very small, someone here recently posted about a little 800 gram female laying eggs.
Now that they are separated, she could just reabsorb any follicles she has, I've heard a lot of people here talking about that.
I'm very glad you can take such good care of them now, and this place is the best for helping you learn what you need to know.
