This morning I found bloody smears in my chicks' dropping. Just smears & not very bright. I just got this chicks Wednesday evening, and I showed the woman I brought them from a sample of the droppings. She confirmed that it was coccidiosis, and told me how to treat it. I purchased Duramycin-10 (Tetracycline Hydrochloride), and mixed 1 teaspoon to 2 quarts of water in their waterer. She also told me to mix a half tablespoon of cayenne pepper to a quart of their food. They are on medicated chick starter. I followed the dosage direction the woman gave me because it didn't give the dosage on the package. I started them on this treatment at about 10am. They are still running around, and eating & drinking fine. I have only seen one more smear of blood so far. I was told to change the water once a day & keep using the medication for 48 hours. The chicks are in a large chicken coop about 8 x 9 with shaving on the floor. I keep it real clean, but I know this hot humid weather can increase the risk of coccidiosis. I tried to post this message before, but it didn't post & I re-typed it. Excuse me if I end up with a double post. Herself I really worried about them. Am I doing the right thing? Is there anything else I can be doing?
