Our goose Ava has been laying on some duck eggs and within the next week they should be hatching. Anyways she must have accidentally broken the outer shell of one of the eggs. I was unable to get to it until today, about three days after I noticed that it was broken. I was going to throw it out today but when I picked it up it was breathing and I could feel it's little body. The inner film is still in tact and it has lived without an outer shell for three days. Do you guys think it will hatch, and have a full life? Should I do something or just leave it alone? Ava doesn't seem to mind it and hasn't tried to throw it out of the nest. Please help!
