Need help sexing 3 American buff geese

[Kandy10]

Hello everyone I need help figuring out what I have in my little group. I for sure have a female because she is laying but I'm not sure which one she is. All the eggs so far have not been fertile

Males are said to have longer necks and overall a bit bigger than the females. I can't tell by your pictures if the one in front is bigger or it's just where it's standing. Though I'm no goose expert yet.

It looks like a trio to me. The bird closest to the camera is a gander, and the two others are hens. It's possible the bird on the right is another gander though. More pictures of them would help. How do they act around you?
