4 of them hatched 5 days ago. The last egg hatched last night. I think someone snuck an egg in the nest a little later. So I hatched the last egg myself and then put it in with the others and she excepted it. I was affraid she wouldn't hatch the last egg, not knowing how much longer it needed to grow. That's why I stuck it in the bator. I can't wait for more. I will be putting some of my ducks eggs in the bator pretty soon. It will be my first time. Wish me luck.
