I have a chocolate hen who has been adding to her nest for 9 days now, the past 4 days she sleeps on the eggs in her nest but come morning she hits the ground running and stays outside alll day. I have never hatched duck eggs before but I know they take 28 days to incubate. I am guessing that these little ojnes developed a bit while she had been sitting on them during the night but then get cold when she is off the nest all day. Is this the way ducks do things or do I have one confused hen on my hands here? She has 9 eggs in the nest and has been acting like she is gonna go broody since there were only about 4-5 eggs in the nest. I am afraid these little eggs are a lost cause now am I right? ETA: correction she only has 8 eggs there, thought she had laid another this morning but she must have stopped.
