Killdeer are easily stressed but if you have to move the nest, the time to do it is with the eggs. Here’s an example of it being done with great care to build the nest back and position the eggs just like the parent bird had them: http://elibrary.unm.edu/sora/Condor/files/issues/v028n04/p0176-p0176.html
We were gone for a few days, and when we returned the eggs were gone. We’re not sure what happened to them as some heavy equipment was being used in the area. We no longer get to see Mama Killdeer distracring us with her “broken wing”. :) Thanks for the information. Maybe it’ll come in handy in the future again. ~KathyM
