I'm pretty sure the Corid is for treatment and the medicated feed (Amprolium) is for prevention. I've heard pretty horrible things about starters containing Amprolium, so can't blame you for not wanting to use it. I'd be worried about everyone getting proper doses by going the treated water route, some birds drink alot more than others. Hopefully someone with a little more knowledge will come along. In fact, this thread may be better suited for the Emergencies section...
Corid has recommendations by weight for treating cocci as well as using it as a preventative 21 day treatment. Where Sulfadimethoxine is the easiest of all sulfa antibiotics on the chickens system, it could still cause permanent damage if not dosed correctly. An avian vet told me about Sulmet and how hard that is on birds compared to Sulfadimethoxine. Everything I've read confirms this, as well as a bad strain of cocci I dealt with once where Sulfadimethoxine wiped it out in a couple days.
I was thinking of getting their digestive flora strong for the first 3.5 weeks with Vitamins-Electrolytes Plus (has probiotics in it) 2 days a week, and at between 3 and 4 weeks of age, run the Corid .25 oz per 1.5 gallons water for 5 days only. Wait 3 weeks while continuing with Vitamins-Electrolytes Plus a few times a week and run Sulfadimethoxine powder at .50 tsp. per gallon for three days only. Then repeat the process. This was a system Mike Strecker used in The Back Yard Flock. He claims to use it up until his birds are 7-9 months of age. Seems an awful long time to me. That's why I was curious as to what system more seasoned poultry men/women use and what their results have been. I thought about posting this in the emergencies section, but I thought since the subject applies to chick raising, this section would be more appropriate.
