What to do with badly placed eggs?

One of my geese has now laid 2 eggs (though I took the first away). She laid the one I took away in a poor location, and now has laid the second one in a pretty equally bad spot. She's made a spot in the grass (hard to call that a nest...) against a barn that is raised about 8 inches off the ground. I'm sure there are all sorts of snakes and other small critters living under the barn that would love to eat the eggs.

I have a huge dog house that I was going to put out for them in the spring, but they haven't seen it yet. I have 8 geese (trio of Embden and Pomeranian, and a pair of Toulouse, which I think laid the eggs) that live outside all the time. They rarely go in any sort of shelter, and are pretty skittish. I would like to move the egg into a makeshift nest inside the doghouse, in the same location, but i'm afraid she will get scared and abandon it.

Also, I know the eggs won't start incubating until she sits on them, but how long should I expect that to be? They don't remotely hang out around the nest right now, and i'm concerned that an opportunistic creature (besides myself) will come and eat it. If she chooses not to sit, how long can the egg be outside and still safe to eat? The high today is 60, and low is 55, and we're expecting rain tonight and tomorrow.

Sorry for all the questions, but this is my first egg!
