My friend wants to take her chicken to the vet

I have a really close friend who has 6 hens. She’s amazing to them, and cares a lot. Perhaps too much, but I’m an animal lover too.

In the past she’s had chickens get bumble foot and treated that. Now, she has a sick chicken, and has made a vet appointment for tomorrow morning. Her husband is not happy about what will likely be a $200 bill.

The chicken is lethargic, laying down, has a closed eye, her tail is down and her neck is pinched in. She was leaning off to the side earlier, and is having watery bowl movements.

She will drink electrolytes if given a little at a time, and she’s barely eaten food with warm water.

We went to the local pet food store (an independent one that deals with different types of animals), but they didn’t know what to do.

It’s been really rainy here, and things are wet.

She thinks it has coccidiosis.

Any ideas or recommendations to avoid a high vet bill? The chicken is two years old.
