Hi there, new chicken Mom as of this spring. We have 12 hens and a rooster, we spotted blood in their poop July 3. On July 5th started 2 tsp Corrid/gallon of water treatment (as the only source of water), then July 12 lowered dose to 1/2 tsp Corrid/gallon of water(directions I followed from Happy Morning Farm). They only eat Nurtrena Nature Smart Organic Chick Feed, and Scratch and Peck starter grit. This picture is from today July 18. I've been doing research and don't think this looks like intestinal shedding but I'm not sure. Could it be a strain of Corrid resistant Coccidiosis and is that treatable at home? Thank you for any insight!
