I lost 3 chickens in a 4 days. I had no idea what was going on. No bloody diarrhea & nothing I could see externally. I sent one off for a necropsy. Tested positive for coccidiosis. I'm treating the entire flock with Corid. But I have 1 who I don't think he's drinking the water. He's standing off to himself a bit. Which is what I noticed with the first couple that died. Is there a concentrated dosage I could give him by dropper? I want to make sure he's getting the medicine, so he doesn't die.
