Okay here's the scoop: We have a duck egg that is missing part of its shell. It had a bad crack in it and it has turned (with some help) into a missing section about the size of your thumb nail. We can see what looks like part of the duckling. The little guy has been peeping to us for 2-3 days, more today. It seems to be alert and is obviously breathing at this point. I've been concerned that bacteria has been invading the shell to the point it would threaten the duckling, but we're afraid of 'helping' it out. Actually I was amazed to find the egg was good and signs of life in it, despite a gross looking crack in it. The discoloration around the crack concerned us. This is a slightly undersized egg from the others. Has anyone had experience where they had to help a duckling out without killing it? I was always told never to help them otherwise they will not grow strong enough from the struggle. How long should we wait... just leave it alone and see what happens?
