I have 5-week-old chicks in my brooder, and I've noticed that a couple of them have soft, foamy poo, which concerns me about the possibility of coccidiosis. I've been feeding them unmedicated feed, which may be contributing to their illness. I have CORID-9.6% oral solution on hand and am trying to determine the correct dosage for 1.5 quarts of water for a 5-day treatment. Any guidance you can provide would be greatly appreciated. Thank you!
