Looks like the raccoon was a young-ish one and didn't know how to get into the egg. On rewind about 2:00 AM the raccoon rolled the egg, then dug under it in the damp nest materials before leaving. Backing up the rewind to maybe 10 PM, the egg looks either damaged or dirty. I vote for dirty, because the raccoon rolled the egg all around and the shell looked intact.
After daylight, the piebald goose cam back and sat again. She is off and on the egg through 11AM. Dedicated.
