sometimes mine would get up off the nest to eat and then when she would go back she would lay in the wrong nest box and I would have to go and put the eggs back under her. Also nearly every time she would get up one of the other hens would go an lay more eggs in her pile...so now she's got eggs incubating that will hatch on different days! I solved all these problems by isolating her. I took the whole nest box and put it in one of my pens. This way there's only one nest, no confusion. I put some feed and water in there with her and locked her in, she's been in there for days and seems a lot happier since the other birds can't mess with her. If you do move her, try to do it at night when she's calm.
