No idea. I'm going to find out. I'm hoping that my atrium pond is done by the time they hatch, but I'll still have some time since I'm not going to throw ducklings into a pond regardless. Can't have them getting waterlogged and chilled before they're ready to swim.Me, too. I'm lurking around, telling myself "NO DUCKS!" and yet they're so cute. And so small. How much trouble could they possibly be?
