Hi All! I have a 6 week old chick who seems to be showing signs of cocci - lethargic, neck stretched, drooping wings, laying down. I've brought her inside, started all chicks on Corid & electrolytes - using a dropper on the weak chick. The other chicks seem fine, but treating all anyway. My questions is this: All the chicks have been on medicated crumbles since day 1. Has anyone ever had a chick get cocci, even when on medicated feed? I though that medicated feed was "enough" for prevention. Does corid work better? Could this be something else? Thanks for any info!
