No Improvement After 72 Hours on Corid…What to do now?!

I have a 6 week old chick that I have been treating for coccidiosis with Corid water and drench. She is not showing any signs of improvement, still hunched and puffed and now shivering/shaking and poops are more watery/diarrhea like. She is eating and drinking, what I consider, a minimal amount. We have been giving her egg yolk as well. Am I hurrying the process or do I need to do something else? This is the same chick I posted earlier this week and will try to link that post with all information. Any advice is appreciated!
 
Has the chick's Corid water been the only water available since treatment started? In a pinch I might try doubling the dosage for a day. Sometimes they can't be saved.
Make sure there is no moisture in the bedding or the coccidia will explode in numbers.

There is a sulfa drug called Sulfadimethoxine used to treat coccidiosis in rabbits but has also been used for chickens. It inhibits absorption of folic acid rather than thiamine like amprolium does. I don't know if you can find it anywhere and I don't know where you live.

Yes, only medicated water available and straight Corid drench just to her. All other chicks are doing well. I removed any damp bedding and continue to do so as I see it, also added more pine shavings on top.

I live in central Illinois and will see if Rural King has Sulfadimethoxine. This is my first go with chickens so I really appreciate your advice!
 
Here's a place to get the sulfa/coccidia drug without a prescription. https://jedds.com/products/trimethoprin-sulfa-medpet?_pos=1&_sid=9ba243557&_ss=r Is this the only chick you're treating? We usually treat the entire flock when we suspect coccidiosis. I would get this chick's poop tested by a vet to be sure you're treating the right thing.
They all drink from the same waterer and it has the medicated water. She is the only one with any symptoms so she is the only one getting additional drench.

I will contact my vet on Monday. Not sure if they do testing of this kind but I will ask!
 
All chickens can drink Corid without a problem, but if you treat her with sulfa antibiotics, you should only treat her. There is a long egg withdrawal time with sulfonamide antibiotics. They are not approved for chickens, but only used off label for resistant coccidiosis and certain other infections. You could separate her in the coop in a wire dog crate with food and medicated water, and let her roost with the flock at night.

She is only 6 weeks old so not even close to laying eggs. I assume her eggs would be ok by the time she starts laying so it sounds like a dumb question to ask but, is that long enough? Presumably another 14ish weeks?
