Junior acting weird

[Raymo2477]

So this is Junior. I thought when I bought her a few years back she was a male, but now I'm positive she's a she.

Tonight she was mounting Jutta (a female) with her mouth open and squeaking like a male.

I'm confused.

Females can have that behavior when they are pregnant or are establishing dominans in the Group.
On the Picture a female on a female for dominans.
