I have a duck not even sure which one laying eggs in a nest seems to be 2 at a time. We found the nest a couple of days ago with about 13 eggs in it and today it is up to 17. If she was going to sit on them would she have already? I don't know how long eggs have been there? We have a some freezing nights also wondering if the eggs are still even able to be sat on if they had been frozen. This is our first year of having ducks that lay eggs so we are not sure exactly what to do with the nest? We have been picking up the straggling eggs.
