I got my 10 chicks from the hatchery Tuesday. They sold me medicated feed and a small container of Amprolium as a mild treatment for coccidiosis. In dogs and cats coccidiosis is an easily transmitted intestinal parasite. The man at the hatchery was telling me it is a bacterial infection the chicks could be hatched with. How do chicks get the disease? I know the hatchery chicks aren't pathogen free but is this disease something I need to be treating for now? I lost 1 chick at 2 days old to something respiratory I think.
