Hen With A Handful Of Mysteries, Please Help!

[aishilemon]

I have a beautiful golden laced wyandotte. She is just over one year old and a complete suck up!
Three days ago now I noticed she was moving extremely slow and not interested in hanging out with the others. She would lay down a lot and stay close to the coop. I've heard that this sometimes happens when hens are about to go through a big brood phase but there are some other symptoms I'm worried about...
She still leaves the coop and comes out when she sees me, and she still walks but is very slow and decides she would rather be laying down near the coop than digging around. What concerns me most is she sometimes looks at worms and blows them off, along with her feed (she still eats bread scraps and slowly picks at grass). She has been drinking a TON and has very loose watery poop with a little plop of orange tinted fecal matter. She did lay an egg two days ago, I'm not sure if she has since.
She is not egg bound, I did check.
She got a nice epsom salt bath yesterday in a turtle pool, to which others jumped in with her (she is not out cast by the flock in anyway)
Her comb and waddle looks beautiful and are in no way out of the ordinary.
No parasites after a thorough investigation.

From the little bit of information you've given us, it sounds like she might have impacted crop. You need to check that. It may not necessarily feel full, but if you feel a hard lump, even a small walnut size lump, you might give her a teaspoon of coconut oil with a massage of the hard lump.

If her crop is empty and flat, you might suspect coccidiosis, and put her and the rest of the flock through a round of Corid.

To get a diagnosis of worms or cocciciosis, you could take a poop sample to your vet and request a fecal float test. If you do this, do it before treating with Corid or you'll get a negative reading.

She could have a bacterial infection. That would require an antibiotic. But you would be guessing. I start a chicken on amoxicillin if I suspect she's picked up bacteria. Often it resolves the problem.
