Grrr, the feedstore sold me chicks and I have had cocci outbreak ever since! I entered them into the big flock without knowing they had cocci, I have lost 2 chicks and one big barred hen. I treated them with sulmet did not help. I brought home oral corid, and I have reconized in the coop a lot of them have poop clearing up, but I still see a couple bloody coops nd I am in day 3 treatment out of 5. Today I have a chick fluffed up like a football isnt moving much, GREAT ANOTHER ONE I BET ILL LOOSE. everytime cocci gets that far they dont make it!!!
