Sulmet is given full strength for 2 days, then 1/2 strength for 5 days, if I recall correctly. Can't do it for just 3 days for cocci. Can't give it by mouth, has to be in the water, but I don't have a bottle for the actual dose since I don't use it anymore.
Corid is the preferred cocci med. Corid is preferred over Sulmet. Sulmet is harder on their intestines, can actually make the bleeding continue longer, and is not effective against all types of cocci. Corid is concentrated amprolium, same med as in the chick starter, but at a higher dosage.
Here are the bottle directions I found online:
Dosage: Poultry: Add 2 tablespoons (1 fl oz) to each gallon of drinking water
Administration: Chickens and Turkeys: Add the required dose given above to that amount of water that will be consumed in 1 day. Water consumption should be carefully checked to insure adequate drug intake. As a generalization, 100 turkeys will drink 1 gallon of water per day for each week of age; chickens will consume one-half this amount.
Coccidiosis (in chickens and turkeys): Medicate as above for 2 days, then reduce amount of Sulmet Drinking Water Solution to one-half above for 4 additional days.
