Speckled Sussex With Digestive Issue. URGENT!!

[HuntingChick14]

I have an 8-10 week old speckled Sussex and her crop has been massive for about a week. She keeps bobbing her head around too. Her beak doesn't smell sour though. I helped her throw up today and it was just her feed that came up and it didn't really smell. I have her inside now in isolation. I gave her water with apple cider vinegar and I withheld her food. What else should I do? She's my favorite hen and I really don't want to have to make the decision to cull her or wake up to see that she's dead. Please help!!!

This is a great article on a whole host of crop issues - a worth while read!
That said, I would probably give her a healthy dose of Nutri Drench. It's one of the best fast-acting vitamins out there (Tractor Supply carries it - not sure who else) and has helped a number of my chickens bounce back from being under the weather.

I took the water away but now I can hear a gurgling sound like somone with an upset stomach and she's constantly doing the head bobbing thing. She keeps fluffing her head and neck feathers when she does this, too. I noticed that her poop was liquid with weird little green things in it. I'm really starting to get concerned that she's not going to make it. She's also holding her neck more deeply towards her chest if that makes sense. Instead of being a soft shaped "s", her neck kind of sharply goes into her chest. It kind of seems like there's something stuck in her throat. Is this actually impaction????
