I have had 100% results with birds recovering from mild cocci symptoms with vitamin treatment. I've never understood denying a sick bird a vital nutrient to 'cure' it. I strongly feel they need to fight it on their own and develop immunity to the local viuses/bacteria. One bird took as long as 6 weeks to fully recover, but now it's HUGE and thriving. He had the bloody diarrhea, extreme lethargy, the whole nine yards. I didn't separate him either, and none of the other chicks with him got sick.
I caught it early though, because I am one of those nuts that sits and watches my birds for a long time. I catch changes in behavior really early because I'm always looking.
ETA: Sorry, I reread this post and it came across as a bit 'preachy'. Not my intent!
That's ok! I'm still learning something new every day. I have 3 kids at home and they take a lot of my time. I realized a couple weeks ago that I needed to downsize my flock. I sold 3 trios last week. I'm happy because I agree with what you're saying and I can manage my flock better now that it's smaller. I feel bad because I noticed that one of my pullets that has the wry neck was not acting normal for a week or so and I feel bad because I choose just to keep an eye on her instead of starting supplements right away. Lesson learned. But I do think medications are ok, when used in moderation (also I don't eat my eggs, I use them as hatching eggs, so that kinda plays into it too).
Speaking of sick chickens, I will update on my 2 sick girls. The one that was worse is on the mend!! No more spoon feeding. She eats and drinks all day by herself. She's preening herself and clucking and acting like a chicken. But her neck is still tilted to the side. I wonder if that is going to be permanent??
The other one has to be put down. If I was not going away, I might give her more time (I've read it can take 2-3 weeks) but her head is totally curled down, up, and under. She can't eat or drink on her own at all. So I can not let it starve to death while I'm away. Wish I would have started treatment sooner!
