Gender of geese?

[NatalieLouise]

Hiya, just wondered if anyone can help me with the gender of these 3 geese? We tried vent sexing them (as seen in photos) but it looks nothing like what we've seen on videos so we're struggling with what sex they might be? Any help would be amazing, thankyou!

How old are they?

they are 2 years old and you havent seen them mating / trying to mate yet? did you just get them? That's how I found out when one of my 6 month olds that was supposed to be female had a penis... you can see it still out right after they mate...

At 2 yrs old the gander will have a slim long neck and a high-pitched honk. The female has a shorter thicker neck and she mumbles . My gander always walked with his head held high my female walks like normal goose.

I haven't had them 2 years, I bought them in March. 2 of them are supposed to be females and one male, but haven't seen them mating
