pullet often laying flat with neck outstretched; trembling occasionally; empty crop; barely eating.

Hey guys,

When we got home yesterday:

1) 6 month old Blue Laced Red Wyandotte pullet laying in run, stretched out. I thought she was dead.
2) Originally when I picked her up, she was fairly unresponsive, checked her over, gave her some water with ACV in it, put her in a box with straw and quarantined her. Noticed she was trembling occasionally, and standing with her head down as if she were looking at her feet. Now she seems ALMOST normal, but is still trembling occasionally and occasionally laying with her neck outstretched, even if this lands her head in the feed dish. She eats a little, but not enough to fill her crop. Crop stays pretty empty. No sour smell, no discharge, eyes are clear and open most of the time. comb and wattles have not changed. There isn't any sneezing or coughing that I am aware of. She DOES seem a bit on the thin side.
3) Since yesterday.
4) No other birds displaying symptoms.
5) No other signs of trauma
6) What happened, if anything that you know of, that may have caused the situation. No idea.
7) What has the bird been eating and drinking, if at all. Purina flock raiser and clean water
8) How does the poop look? Normal? Bloody? Runny? etc. Light green color with white on top. No blood, perhaps a bit runny.
9) What has been the treatment you have administered so far? ACV, Vitamins and probiotics(savachick), and Oxytetracycline.
10 ) What is your intent as far as treatment? No vets, We'd like to treat it ourselves, just didn't want to throw a bunch of meds at her that weren't necessary.
11) I tried to take video of the trembling, but, of course, she doesn't do it when I have the camera out.
12) Bedding is pine straw and wheat straw. Housing is a typical, coop with plenty of ventilation.

She's on of our best pullets and we'd hate to lose her. Thanks for any help or suggestions.

Does it sound like she has wry neck, where her neck seems to be in a muscle spasm down or to the side, or does her neck seem limp? Could she have gotten into something toxic like dead animal remains or buried vegetation? Check your feed for a funny color or odor, in case there is mold. She also could be dehydrated and weak from something like coccidiosis. Cocci symptoms are lethargy, hunched posture, not eating, and diarrhea or bloody stools. Corid (amprollium) is good for that. Look her skin over for signs of mites or lice on her skin. Was she vaccinated for Mareks disease?

Thanks for the help!

She is seeming better today, though still not 100%

I don't think it's wry neck, more limp neck. I checked her and everyone else for mites today, didn't find any. I did consider cocci, but her poo seems normal, besides the green color. Our local TSC didn't have any amprollium, we had to order it offline. :/ There were even signs up notifying customers that TSC won't be carrying it anymore.

She has not been vaccinated for Marek's.

Their bedding is usually pine straw we harvest ourselves, but the past few weeks have been so wet that we have bought straw from the big box stores, but considering the green droppings(possible liver issues), something toxic being ingested is as good of a guess as anything else; that or Cocci, I guess, or maybe something was stuck in her throat like a piece of fluff or something.

Hopefully she'll continue to do well and get better. How long do you think we should we keep her separated?

Green droppings are usually a sign of not eating much. Botulism is the disease I had worried about if her neck was limp. It usually starts with weakness of the lower limbs, followed by wings, and then the neck. If you have some electrolytes with vitamins, I would use them in her water. I hadn't heard anything about amprollium not being carried by TSC. It is a cattle medicine that us used to treat scours. Hopefully, that will not happen.
