Can anyone tell me how often I can add AMPROL to the water of chicks that seem to keep having outbreaks of cocci? How about the sulfa drugs SULMET and SULFADIMETHOXINE? I think i may have overdosed my chicks switching back and forth between the drugs trying to get rid of the cocci. I can't find any information about frequency of use. Someone told me I could use AMPROL as often as I wanted that it was very safe. I didn't use the drugs back to back with no resting times, I did have times when they were getting a lot of probiotics and other good things, garlic, yogurt, ACV, DE. But I may have overdone it with the drugs.
