Will Sulmet harm chicks if they don't have cocci?

[PoultryGirly]

Hi. I have a chick that is acting lethargic (puffed, eyes closed, etc) that is about 2 weeks old. I put Sulmet in ALL of my chicks' waterer. If the chick(s) actually don't have cocci, will the Sulmet harm them?

Sulmet is rough on chicks whether they have cocci or not. It is rough on therir intestinal tract. I would give a small amount of plain yougurt both during and after treatment.

Now I'm really worried! Will it kill them?

I just gave them the liquid Corid. I put 9.5 mL in a gallon. Is this the right dosage? Also, the sick chick is perking up a bit. He/she is grooming him/herself and eats! I also dipped his/her beak in the medicated water and he/she drank some.
