Hen can’t close her beak

[TSA]

If she will not voluntary drink water you might have to try to help her get water down her.
If that does not work use a wet rag and try to wipe some dirt of the outside and inside of her beak. Hope this helps.

Is it definitely dirt?
No possible sore in throat?

Can you smell her mouth?
See if it stinks.

Didn’t see any sores, there was some mucus looking stuff

Clear

Are you sure she isn't hot or stressed and just keeping her mouth open to breath?

Can you see her tongue?

ETA. I looked at you pics again.
I think I see it in one.

I'm pulling at straws here..
Could she have injured her jaw?

I'm at a loss.
