Weak hen not eating

[Nasnro]

Hi all, I have a two year old barred rock hen. As of yesterday I came home from work to find her very weak and not moving. She had green poop stuck to her feathers around her vent. I gave her a bath in and found small white specks.
I put her into a hospital cage and gave her feed and water. She ate a very small amount but didnt drink anything.
I'm looking for any advice on what to do, I've never seen anything like this before.
Thanks in advance.
Edit: Went out to check on her and she seems to be loosing balance and falling backwards

Sorry about your sick hen. Can you post any pictures of her vent and her droppings? Did you get the droppings off to clean up her vent? Is there any evidence of a vent prolapse or pecking? Were the white specks you saw moving slowly like tapeworms segments would look? Has this hen been laying eggs recently? Has she lost weight in her breast or has she developed any fluid or enlargement of her lower belly?

I would offer some water with electrolytes. B vitamins including riboflavin and thiamine would be good as well. Cooked chopped egg, tuna, and wet chicken feed with a lot of water are usually good things to try to feed. I hold the food close in a small bowl, so they can see it. Dehydration could be a problem, a leg injury, or some type of internal infection might cause her to lose balance. Reproductive infections and internal laying are common in hens 2 and older. Try to see if her legs are both moving well.

I recently nursed a hen back to health after she lost balance for over 5 weeks, and could not walk around. She is now walking everywhere and eating normally, but I still don’t know the cause.

Thanks for your swift reply, unfortunately as I'm writing this the hen has passed away. As a precaution I'm going to get a dewormer for the rest of the flock and bump up on their minerals. Any other ideas to prevent this would be greatly appreciated. Thanks

Unfortunately it is hard to know what killed her without doing a necropsy or autopsy on her body. Many poultry colleges or labs will do them. Many of us do necropsies at home, just to have a look at the abdominal organs (intestines, gizzard, liver, oviduct, spleen, and others.) If you do this, take pictures to post here for any comments. The pressence of yellow fluid when opening the abdomen, masses of egg material, a discolored liver, worm masses inside the intestines, or tiny tumors on organs can give us a clue on shat went wrong. Very sorry for your loss.
