HELP! Drinking too much water and looking bad.

I need some help. This is the second time that I've had a 2-3 yr old hen get sick this way. She is lethargic, tail half way down, puffed up a bit, loss of appetite, and the key symptom to both hens is drinking a lot of water. So much that when both were picked up, they puked water on me. A year and a half ago the first hen was sick for 3-5 days and recovered. She was later given away. But now this hen has the same symptoms. She was attacked by a gosh hawk and was antibiotics for her wound for seven days. Her wounds healed nicely, with stitches out on day 10, she was perky and well. Day 2 after ending the 7 days of antibiotics, she looked sick. I gave her some warm watered food with corn, calcium, and pro-biotic. She was almost back to her perky self again 4 days later...then today...crash...same symptoms. Does anybody know what causes this? Could it be bacteria in the soil? The other hen is fine and has been with her the whole time with no symptoms. I know it might be possible to wipe out her immune system with antibiotics, but the first hen hadn't any and why isn't her friend hen sick? She is now quarantined in the pen for a week while I'm gone. I hope she doesn't die. She is the coolest chicken.

They can't drink too much water. If they are drinking a lot, they need it.

What has been their main feed for the 3 years? Has she been laying consistently?

Why did you give the calcium?

She could be trying to flush her kidneys.

If she was my hen, I would treat her for coccidiosis. The antibiotic could very well have stressed her digestive system, allowing the protozoa to have a population explosion.

Do not give her any more calcium right now.

Rat poison will cause animals to drink a lot of water. Any chance of that? Maybe a neighbor uses it?

You say you picked her up and she regurgitated - how does her crop feel? Could it be a crop issue? How do her droppings look? Is she eating? I second the suggestion to treat for coccidiosis. I had a girl with a severe cases of coccidiosis and her symptoms, including regurgitating if I wasn't careful how I handled her, were very similar to yours.

The OP hasn't answered any of our questions so perhaps the problem has been resolved.

I'm sorry for not responding earlier. I had to leave for a week and had a chicken sitter watch over her. She isn't a big layer anymore and she was healthy and recovered for a week while I was gone. I stuck her in the tractor again only once. The ground is moss, a bit of grass and very little trailing buttercup, which is poisonous, but never affected them before when they ate it. None of it looked eaten.
This will be the 3rd time she has been sick like this in 3 months. I'm pretty sure it has something to do with the ground.
She has been on Walmart food. Egg maker. most of her life, and is supplemented with spinach, small amount of scratch grains, deer protein, and occasional cracker. She is on a controlled feed cause usually she eat till she falls over, its her nature.
Its an isolated yard, no poison or fertilizers used in the yard.
She now has been sick for 3 days and has almost stopped eating. Accept for crackers, she chows down on them.
Had the vet do a fecal smear and said there wasn't any parasites, or coccidiosis present.
She is not looking good and I'm taking her back to the vet today to test for bacteria via cloaca swab.
I don't want her to die, but if she does, I want to know what it is. And also inform others of this.

The other chicken, has not cleared up from the red butt, nor is she sick. Diatomatious earth, and ash baths were initiated every day for a week with very little change. These black broiler are known to have skin issues and it just might have an allergic reaction to the cedar chips. But I did find out that she might have "depluming mites' which are very hard to get rid of because they are at the base of the feather shaft and irritate the chicken enough to pluck out their feathers. They also bite the surface of the skin feed off the pus the skin ewes. Causing redness. When it gets warm out, I'm going to try food grade mineral oil around those red areas and feather shafts. Then bath her after and hour or two. She loves the warm bath, which is probably a relief.

Thank you for responding to my post and with more facts, please feel free to help...I'll keep you updated no matter what happens.

She's still the same, not eating very much and pooping very little. Lots of white in her poo, little bit of bright green. Watery.

I have heard that chickens with Coccidiosis will drink a ton of water. Plus, with the puffing and hunching, that would be the first thing I treated for.

Corid treats all nine strains of Cocci... It comes in 20% powder and 9.6% liquid. It is fairly readily available at most local feed stores, Tractor Supply, and online.

Dosage:

1.5 teaspoons (NO LESS) of 20% powder per gallon of water

OR

2 teaspoons of 9.6% liquid per gallon of water

Make sure it's the only water your birds can access for 5-7 days during treatment. If you treat one, treat your whole flock.

Is she still drinking water like mad? If so... it could be the perfect time to give her Corid water.

Super runny white urates can also be a sign of kidney issues... I hope it's "just" Coccidiosis.

I am sorry for your troubles.

Edit to add: I assume you've checked her over for mites/lice... Do you feel any hardness in her abdomen? Does she feel "full" and unusually squishy like a water balloon? When was the last time she laid an egg?
