Black head?

[Csyoder]

I have a black Austrolorp chicken about a year old. She has been very healthy but this am is acting lethargic and her poop is runny with this green/yellow hue.
They are in a coop with access to an open and closed run. Pine bedding.
I checked her vent, skin and her crop and all look normal. Her comb is still bright red too.
Could this be the start of black head?

When was her last egg?
Is her crop emptying?
Has she been dewormed?

Since she's acting lethargic, I'd start her on Calcium asap. Give 1 Calcium Citrate+D3 now, then once daily for a week, see if she expels an egg or other material like Lash.

Awesome. Is that usually at rural king?

I am not sure when he last egg was. They lay all over. I do know we don’t have every hen lay every day.

Her crop is emptying. I saw her eat and drink some electrolytes yesterday. And stand up to forage a bit.

I did give her ivermectin. I had not dewormed them yet. I was following advice from a friend who has had chickens for years and never wormed them. This is my first time. Will be treating from now on. I have now treated the whole flock.

You can find Calcium Citrate+D3 at stores like Walmart, CVS, etc.

Some folks deworm, so don't. Getting a fecal float through a vet can often let you know if deworming is necessary, but sometimes it's hard to find a vet willing to test a sample of chicken poop.

To treat most worms that poultry can have except for Tapeworm you can use Safeguard Liquid Goat Dewormer or Equine Paste (Fenbendazole) or Valbazen (Albendazole). Both are given orally by weight; they do not mix well with water.

Safeguard dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.
---OR---
Valbazen dose is 0.08ml per pound of weight given orally once, then repeated in 10 days

Here's how to give oral medications:
