This just happened last week remember where the member's child scared mama wood duck off she flew off and the member got the ducklings I think she had them overnight and then mama wood duck returned and they had a reunion.I'd keep an eye out for the mama wood duck. I can't imagine this tiny thing strayed that far (although possible) so maybe mama isn't too far away. If you take it outside, while keeping it safe, maybe mama duck will hear it and come to take it back. Just a thought
