What gender are they?

[HENS-and-MARES]

I have 3 Toulouse geese that were supposed to be 2 females, and a male. Then the females started mating with each other and the male mothered some goslings.
What gender are they?
This is the almost confirmed male.
He mates with the other goose.

this is the almost confirmed female

This is the one I have no idea about.

Its totally normal for ganders to guard "mother" goslings. Also females will mount each other to establish dominance.

Adult geese are very east to vent sex if you want to give it a try. Also most can be sexed by voice. Females tend to be louder.

I’m pretty sure that the first 2 geese are a male and female, based on behavior, so the last one is really the only one I’m wondering about.

What are your thoughts based on appearance?

Last one looks like a male to me

Would it help if I said that the last one is at least 1 1/2 years old, and is smaller than my 20 week old Sebastopol goslings?

Sit and listen to them. Almost all mature geese can be voice sexed.

What does a male goose sound like? What does a female.

Males have more murmered voice. Females are sharper and louder.
