Hi! I was away from home for a few months and when I came back, a duck had made a nest beside my driveway. I visited home 10 days before I officially moved back and she wasn't there yet so I can't say for sure how many days the eggs have been there but at the very least I have been home for 31 days. She sits on the eggs most of the time, only leaves to find food for less than 1 hour per day but in the time she was gone I saw that there are 17 eggs!! Online I saw that it takes 30 days for a muscovy duck egg to hatch and now it has been more than that...is it possible that all 17 eggs will not hatch? Keep in mind it is possible she laid them as much as 9 days before I got home which would make the eggs closer to 40 days
