1.5 y/o Buckeye corid with probiotics?

[BugStalker]

After https://www.backyardchickens.com/threads/easter-egger-moulting-question.1416928/ a 1.5 yr old buckeye started moulting and I found a blob of blood on a new feather shaft, so I separated her with the other one. Unfortunately, I didn't notice the sun was getting low enough to not completely dry out the whole area until I started smelling mouldy grass. Ivory had diarrhea. I moved them to full sun and gave her yeast-fighting stuff and probiotics, and she improved, and has been gaining her weight back, but the Buckeye then had diarrhea. Instead of improving on the same treatment, it became water only. Docusate sodium, calcium and magnesium didn't work. I tried baking soda flush, and the tube pulled out something like haylage. She then improved on the treatment, along with extra calcium and magnesium, but while her weight loss slowed, she was still losing weight. Remembering that coccidia multiplies fast in wet grass, unsure if I found coccidia oocysts in the fecals, and considering the age of the birds, I put them on corid last night. Unfortunately, it seems to be competing with the probiotics, making Ivory's droppings wet again.

Here's the Buckeye's latest

Here's Ivory's latest (I picked off the top white part with a leaf, and smooshed it out, before thinking of taking a picture.) The top right corner is still wet from a very wet one with almost no solids after the buckeye drank a lot of the corid water.

Any advice? Should I keep up the probiotics and corid both, discontinue one or the other, or do something else? I'm looking into fecal float testing for coccidia, so links for that would be appreciated, as well. I saw some very small things at 300x that resembled pictures of coccidia oocysts in a slide that had dried a few hours, but when I went back to confirm, I couldn't find what I thought I saw, and haven't found them in new floats...so far... I thought about trying ACV as well, in case that would help the gut Flora...

I think I will just continue them both for now. They hadn't had their probiotics yet today, though Ivory had seemed to do fine without not long ago. Only gave to her because it was easier in the water. I should also start the yeast stuff again, I guess. I might still try ACV, first, for something different.

Ensure there isnt any thiamine in the probiotics. It will cause the corid to be ineffective since it's a thiamine blocker.

Ivory is pretty much back to normal, but I think the buckeye may be reacting to zinc oxide, (https://www.backyardchickens.com/threads/zinc-oxide-poisoning.1422149/) so I am thinking of stopping the corid to reduce kidney work. Any advice on stopping corid after only 2 days?

I forgot to say they both had slow crops. It looked like the buckeye was impacted, which is why I did the docusate sodium, etc. She seemed to be getting better on only 12mg extra zinc, but then became tired, so I gave more for energy. I also gave her some when I stopped the vitamins for the corid.
