I have four five week old chicks. I am feeding them medicated starter grower feed. Most poop is normal but one (and I’m not sure which one) has watery poop. I thought at first it was because they were drinking a lot of water. But I have been reading that I should perhaps start them on Corid. All are acting very energetic and completely normal. Eating well, and I wash the waterer and give fresh every day. I thought the medicated feed would prevent coccidiosis. Not sure what to do or if I should be concerned. Please advise. I am going away for 3 days and leaving them with a chick sitter. Worried!
