I'm glad you were able to get your little girl feeling better again. Anytime you see them standing like a vulture and not eating and they are still juvies there's a good bet its cocci. I hate cocci. We went through some nasty resistant cocci here last summer. The good thing is, once you deal with it, you will be able to spot it a mile away the next time. I would give your girl some time before trying to deworm or anything. Wormer is hard on chickens especially sick ones. She is probably just eating to make up for starving lol.
