Pretty sure we have lost two chickens to cocci. Bloody stools and lethargic before they died. It was very fast. One evening they were sick and the next day they died. I went to our local farming store and bought Di-Methox and Oxytetracycline HCL at the direction of our local vet. He did admit however that he was not well versed in chickens. I want some opinions on these medications. Also we have two Nigerian Dwarf goats that live in a pen next to our chicken pen and they had cocci a few weeks ago. We treated them and they have been fine since. Could our chickens have caught the cocci from the goats?
