One of my ducks is sitting on her first clutch!!! Now normally a duck will build up her eggs over a period of days, not sitting until she feels she has enough. That keeps the eggs from starting the incubation at different times. This duck however, started laying, has 11 eggs and only got off the nest for 20 mins to a half hour each day.... So, best I can tell, if all these eggs have been incubating for 11-12 days, at 1 egg a day.... So how do I handle this as time progresses???
