I used corid and my chickens still have cocci. Bloody poop, dont act sick tho. I called every vet i could here and NOBODY LOOKS AT CHICKENS. Ugh, i heard if i use sulmet i cant eat the eggs later. Is this true? I used sulmet on three goat kids who had cocci and i saved them all. I dont know what to do. I have diffenent pens with chicken breeds seperated.
