Shell-less egg with weird stuff stuck (pics)

[Mrs Wick]

Hi, my hen was becoming lethargic.
Yesterday she layed a softshell egg. I de-wormed her with levamisole.

Today, she didn't move at all, and layed a shell-less egg with white weird stuff (see picture).
She lost appetite.
Should I give her medicine ?

Her poop is always like a long foamy tube (see pic).

I de-wormed her with levamisole.

How long ago and what was the dosage?
@dawg53
How old is this bird?

Most likely the hen has some type of bacterial infection either in the reproductive tract or digestive tract, nothing to do with the Levamisole.
SMZ-TMP aka Septra/Bactrim might help.

she is 1 yr old
I de wormed her 3 days ago

What dose do you suggest, and for how long ?
I have bought SMZ TMP 200mg/40mg syrup.
