If you incubate a goose egg and it hatches does it think your its mom?

When a goose imprints, it BECOMES the species it imprints on. When it imprints on a human it KNOWS that it is a human, and if raised with humans nothing can change that. A goose will usually imprint within the first 24 hours, but if the goose is socialized with other goslings soon after, the effects will start to wear off. It doesn't happen immediately, but it happens rather quickly.

Here is some more information on imprinting that makes it even more easy to understand.

First of all I love the American spelling of Mum...it's cute.

umm Not quite. If you feed it and look after it it will think you are its mother...or father given the father goose generally helps the mother raise the babies.

Basically, you don't need to site there for hours on end waiting for it to hatch so it can see you.

Yes

Its supposed to be that the first thing it sees (person,animal) thinks it it's parent.

Sure is, and it follows you around until you make some kind of barrier.

I think so.
