You might not be too successful moving the goose but I cant see the chickens being much bother to it. If you disturb her nest she may abandon it and lay in a new location more or less to your liking.

Thanks, I'll leave her there and let nature take its course.

Yeah, she will probably do what fancifowl says. I discovered a guinea nest awhile back (outside) and was keeping an eye on it. Today I noticed 4 egg shells where a predator was eating the eggs, so I took the remaining ones away and put them in another nest that is close to the dog. Hopefully the guineas at that one will keep laying eggs in it and someone will go broody on it! Birds can be so un-coop-erative sometimes....
