Chicken can't stand/walk + one leg doesn't move

[Amazing_chicks27]

I've got a problem with one of my chickens who can't stand or walk. It has been a few days ago since this has happened, I don't remember when but I found her on the ground, laying on one side. She seemed very agitated. At first, I thought she got into a fight with another hen. After giving her some electrolytes, she seemed more calm. She would eat and drink and at some point she was able to stand. But now, she can't stand at all, she tries to get back up but just can't. This afternoon I went to check up on her and she had her eyes closed, I tried to give her electrolytes with a syringe without needle, but she wouldn't allow me to. So I put some on the cardboard and she would drink a little bit. I haven't seen her eat. Her droppings are diarrhea like and very smelly. I have no clue why she can't stand and what caused it. She was perfectly fine but these days she can't walk. Any ideas of what it can be?

I have added some pictures.

I'm sorry about your hen.

She looks to be in very poor shape. I would consider putting her out of her misery.

If you want to find out more about why she declined, send the body to your state lab for analysis. https://www.metzerfarms.com/poultry-labs.html

She made through the night. I noticed that she has a wound on one of her legs today. I hope it isn't something serious. Also found white stands of I don't know what. I want to give this hen a chance, she seems to what to live. I want to find out what is going on. Because it is sickness season or what?

Looks like a roundworm in the poop but likely this is not the cause of her decline. Her overall condition in the photos is poor.

You can try deworming her to see if that makes a difference. You can find Safeguard Liquid Goat Dewormer at stores like TSC.
Safeguard dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.
