7 month old mallard, clipped wings has left the yard, would the cold winter bring her home

[milkweeds]

I clipped all my 7 month old ducklings ....... One duckling got out of the yard and went to the farm next door. I don't think that farm will supply her enough food for the winter to sustain life...as there are not animals there , just an old barn and garage that one can crawl under and 2 ponds that are beginning to freeze over.......so I am wondering if anyone has had any experience with mallards to know what she would do , come winter. She knows how to get home because she has come back and forth a few times...but she refuses to stay. So I am wondering if a young mallard , when faced with no food and severe cold would come running home since I am only about 600 feet away?.....anyone had this happen. I worry since she cannot fly.....she cannot migrate and so she is stuck on the ground with winter coming.......I am in Caribou Maine..where you can almost see Santa's house.

If she has done it before. I'm pretty sure she will return or you will have to go get her.
