Something wrong with this rat?

Okay, so for about a day one of my female rats has been acting like a male. Like a male with a bunch of females. I keep seeing her do the whole mounting and chasing routine my big breeder male goes through, and I KNOW she is a she and not a he. No big testicles, sleek and light body, nipples, everything female.

But she's acting like a male. Even doing what looks like a successful copulation (excluding lots of groin licking afterward from either rat), and I've seen some intense romping around from my girls, but not like this.

Ideas? I'm starting to wonder if I've got a female who had something go wrong in the womb.
I don't think I could get a video of this. I could TRY, but lifting the lid on the bin would grab too much of their attention.

She's just being alpha rattie. It' a dominance thing. My 2 boys do it all the time.

That's what I thought, but she's actually getting into fights with the two girls who ARE pregnant, and I've never had this sort of dom fights quite like this. The oldest female (who is one of the preggers) is actually puffing her fur up, so blood might start showing up, which is why I'm asking. Just not quite normal.
