Imprinted gosling - any way to get it back with its goose family?

[The goose girl]

My neighbor's 1 year old goose pair hatched four goslings over a period of at least three days. The fourth gosling had just come out of the egg when mamma and pappa goose decide to leave the nest with the other three. It was on its back, not able to stand up or walk, and getting cold. Humans then decide to take it inside under a heating lamp to let it gain some strength - it was not possible to connect a lamp outside. It was considered to take another gosling inside as a buddy, but the little one seemed very weak and it would only add to the problem if it died and left its companion alone.

So, gosling gains strength over the next 36 hours and is physically ready for a family reunion - but it's now imprinted on humans. Goose family wants it to join them, but gosling wants its humans and screams bloody murder if left alone with goose family. The screaming starts stressing the gander and he begins to pick at the little one. Little one is once again carted off to safety for the night - so now what to do?

Has anyone here experienced the same thing? Is there any chance for a not too distant family reunion? What did you do? Any dos and don'ts?

Try putting a mirror in with the gosling.

Separate the gander from the flock and reintroduce the gosling to the female and other goslings. After the baby has calmed down reintroduce the gander. It may take only an hour, at most maybe a day.
Another thing to try is bring all the goslings inside and let them sleep with the new baby overnight, “they’ll be fine together” then reintroduce them to the mother in the morning. The baby will bond with the other babies, and those goslings will teach them not to fear the parents.
Keep the gander away until the new baby has relaxed around the mother.

36 hours old isn’t long enough to make a lifetime impact, even a goose raised only with humans for years can rebond with other geese.

Try putting a mirror in with the gosling.

Try this, and once the gosling starts 'talking' to the mirror reintroduce it to the flock.
