Bloody Poop- How to treat chicks and ducks?

[Rosie42892]

I know that more then likely one of my chicks has Cocci, based on the bloody stool. I have chicks, ducks, and geese in close quarters. I know that I need to treat the chicks with Corid

Would that be the correct one?

Should I treat the ducks and Geese? Is it safe for them to have the Corid? Thank you for any help!
