Rabbit injury/prolapse?

[whiiiterabbiiiit]

Can anyone help me identify what is wrong with my rabbit? I do have a vet appointment later on.

Poor little love. Do you have multiple bunnies living together?

Two, I wonder if they have been fighting. I have separated them.

I'd take the rabbit straight in as an emergency - they are a prey species so hide pain very well and can go downhill extremely quickly.
