Should I refill her laybox???

[LED]

Alright, I have a female that I think is about to lay, She is starting to Dig a lot in her LayBox and she's dug all the way to the bottom/plastic. I just wanted to know If I should Re-fill it alittle or would it be alright to leave as is? The pics of her are about 3-4 days old. She has been in her laybox all night and isn't eating, which leads me to think that she is close?

Here are a few pics of what I'm talking about...

I do not refill any of my lay boxes until the female is done laying for the year.
