Another thing you can use for coccidiosis is cayenne pepper if you are afraid of the drugs. Sprinkle 1 tbls. on their food and if possible mix it. that way everyone gets it. You can use this everyday, It can't possibly hurt them and in fact provides some good vitamins for them. My birds see the food with the red from the pepper and they are just all over it. They don't have the taste buds we have so can't feel the heat. Do you use ACV? This is another thing that makes their guts an unpleasant place for cocci. As rotten as the oocytes are they also need a certain enviroment to live and reproduce.
How bad is the cocci in your flock? If it's bad use the Sulmet.
