I didn't realize that they had a nest but saw one duck alone a lot, and they are always together. Finally we found the nest. They made a nest outside of the coop and have been staying on the eggs all day but when we call them at night they come into the coop. They have been doing this for 3 days and have 3 eggs in the nest. It has been down to the 30's at night while the eggs have been unattended and I am pretty sure that they will not make it. How many eggs will she lay before she goes all the way broody and quits laying eggs? Should I move the eggs into a safe place for her, separated from the rest, so that she can finish laying and be safe?
