My husband works in Metro DC. A huge office building complex in the middle of a concrete jungle. Going out at lunch he found a momma duck and 9 ducklings foraging around a break area for food. The female is greyish brown with white lacing. I have no clue what she might be. He took the mother and ducklings around to a sheltered area of the complex where they wouldn't be run over and could eat. Would it be wrong for him to bring her and the ducklings home and turn them out here to be fed and cared for? Or leave them to forage for food scraps and possibly run over by traffic?
