Thanks, I did miss cleaning the wooden thing you can see she is climbing on now
And she was climbing on it before I washed her, so I guess its possible there's some scent on there.
I think I'll just do a thorough clean again, and a bath.
Really need one of those things that shows up urine stains under UV light, but for egg scent instead.

I only just bought 15 150-250g rats, I might have to get something smaller too.
I don't like the idea of assist feeding cause it probably makes things worse, but that's a last resort I guess.

I'm wondering if its stress, but at least if she's hanging off the guard thing, she's not moving all over the place
