Hen Sick

[CarsonDM]

My hen was fin this morning but now is blowing bubbles out of her mouth and won’t stand. She also hasn’t been laying any eggs.

I'm sorry about your hen.

Do you have any photos of her and the inside of her beak?
Have you noticed if she's sneezing, has respiratory symptoms?
Is her crop emptying?
Does she have any lesions or canker inside the beak?

It sounds like she's very sick, if vet care is an option, that would be best.
