Reminds me that I need to go out and check to see if Dorothy, the mallard hen is back. She has hatched a clutch every year for five years now in the atrium outside of my office. We put out a wading pool, for the ducklings to use, until they get a few weeks old, and then capture all the ducklings, and put them in their wading pool in the back of a pickup, and transport them about a mile to more natural waters.
The first year Dorothy was really upset by the whole ordeal. Now she just circles above the truck until we get to the water, and put the ducklings down. Then she lands about ten yards away and quacks until they all gather on her, before she takes them into the water.
