So how long will it take for them to hatch?

[Harley's girl]

My goose has not got up since Monday or Tuesday. I think (I have not dared to lift her up to see) she has 9 eggs under her, maybe 10. So if she is now setting how long does it take? I have no clue about geese. But I am wanting to know how long it will take!

I am very excited about these goslings.......when I got the geese I was told they were sisters.....but I found out they are a pair!

I was so excited and now goosy butt is now a broody butt! LOLOL

Thanks!
