Amprolium is what's in most medicated chick starters and it is *not* harmful.I NEVER use medicated chick starter. It has harmful stuff in it that I just DON'T trust. I hope she gets better.
I would use Diatomaceous Earth(DE) cause it is natural and not harmful. She probably doesn't have mites or parasites, cause she is just a chick. Is she living in the house?
