rabbit in labor all day

Question
We have a Neth. Dwarf doe in labor.  It's been going on for 12 hrs.  She pulled hair and made a nest, but nothing is happening.  She has been in hard labor on and off, with squeeks/grunts with contractions.  She's not in the nest box anymore, but resting/sleeping in back corner.  She's alert at times and has eaten a bite or two of oats, but otherwise is tired.
Is there anything we can do to help her?

Answer
How is she doing now? Has she had the babies? Is she still in labour? If she is still in labour, she really needs to get to a vet to get a shot of oxytocin or to otherwise be assisted as needed. Since rabbits are so small, it is generally dangerous to reach in an help pull a kit out unless you know what you are doing or the kit is already dead and partway out.
