When do geese give up?

[Lila123]

For context I asked for two girl goslings so I didn’t have an issue with breeding but it is what it is and I love my goose and gander as they are.
My geese have grown up and are getting it on. They’ve built a nest and are laying eggs in it, so I’ve been swapping their eggs out with infertile duck eggs. I only want two geese and my property can’t support more and also they’re siblings.
But my goose is now sitting on the nest so I can’t lock them up at night anymore because they won’t leave it.
How long will she sit on them without them hatching?
As in when will she give up so that I can put them away at night and not have to worry about predators getting them at night?

Thank you

Just take the eggs away. I pick up my goose eggs daily during the laying season.

Agreed, take the eggs away. There’s no point in them spending time and energy on eggs that will never be.

And predators will soon find them.

Thanks all this has been very helpful. I’ve been confiscating the eggs and they’re back in their house at night now
