Can you tell your geese apart?

I'm sure it'll become much easier when it's their first egg laying season

It’ll become more obvious before then based on their behaviors and voice, Shell be more cackly, he’ll have a loud honk, he’ll also tend to want to keep in between her and everyone else.

Once they are "mature" it should be fairly straightforward. Sometimes at a distance I'll have to squint, but I can say with absolute surety I've never mistaken the gander for the goose. Appearance, behavior, voice, etc are all different.
