Were they vaccinated for coccidiosis or for Mareks? There have been some threads here on BYC of cocci in vaccinated chicks. Most of the vaccines vaccinate for the most severe strains of coccidiosis, but not all 9 strains.

Both I believe. I called the breeder today and she thinks I should just cautiously watch right now so far no more bloody poos they are all eating and drinking and running around like chickens. If I see one more bloody poo I'm going to give them the corid to be safe.
