Kathy, my vet had indicated if I got the liquid I'd need to dose the chickens individually. Or do you mix that with water too? I may be getting the antibiotics confused with the corid... :/ /
Corid can be used as a drench, but I never have even though I prefer dosing everything orally. I would dose them orally if they weren't drinking. Call your vet and double check.
