Hi there. Woke up to bloody poops in the brooder and a clearly unwell chick. She is isolating, fluffed up, and even though she doesn’t have a red comb yet, her comb and face seem pale (not the usual vibrant yellow color). She is on a medicated chick feed, so is it possible she has coccidiosis even though she’s on amprolium? She’s 4 weeks old, isn’t showing any other symptoms. There are three very vibrant chicks in the brooder with her, all who are acting and looking normal. Please see pics and advise. Thanks!
