I'm not sure what the answer is but if it were me  I would leave well enough alone... Let her roll them around, she may or may not sit on them but just leave the eggs there for the pair to do as they see fit...

 

Eventually you will know when to remove them as there will be no interest shown...I have so many questions I'd like to ask only the object of the post was you wanting to know how to make it comfortable for her... It seems since you have offered a "box" she is interested in making her own nest... Looks like she wants to "do it alone."

 

Here are some pictures...

What sweethearts.  Thank you for rescuing them and giving them a fighting chance.

 

Both clutches of Cockatiel babies at this house came in a disposable Glad container with some of that paper bedding for hamsters.    She sat on eggs in a nest one time and abandoned them a few days before they should have hatched so I never went the nest route again. 

 

Your setup looks good.  She might like some loose paper to settle on, though.

 

Good luck!

What beautiful birds!  Thanks for sharing the pictures.

 

I know nothing about tiels.....Maybe Erika will be along answer your question.  di

 

Well, here's an update!  5th egg was laid this morning and the parents have moved into their wooden nest box with pine shavings!  Here's a picture of them nesting.  I think it's sweet that when momma goes to get some food or a drink, papa is close by and goes with the eggs.
