The hatch I caught on video (sorry it was so wiggly) was just how I'd read it goes. The hen began sitting in the doorway of the house, intensely scouting the area, and then going back in. I noticed her doing this, and wondered if maybe this was the morning. After about 30 minutes of this, I guess she was satisfied. She popped out, and flew down to the water just below the house. I couldn't hear her doing it, but she started calling to the ducklings. And they started hopping and scrambling to reach the opening, and all 10 jumped out within just a few minutes. They stuck to her tail like glue, and she took them across the pond to the cattails along the dam.
