How do you get the goose off the nest the egg has been there 5 weeks?

Are you sure you have the exact date she sat down on that nest correct?

It is possible for a goose to go up to 35 days on the nest before her goslings have hatched.

When a goose sits down on her nest it does not mean that she immediately drops the eggs into it. Most Canadas will sit on their nest one week before beginning to lay the eggs and the eggs take a day each to lay.

If you are positive that she has been on a layed egg for 35 days, you need to contact a wildlife rehabilitator. Call immediately if she is sluggish, keeps her head down, feathers puffed up or has a vacant or tired look in her eyes. She is ill and is need medical attention.
