Puffy face AND diarrhea? Help please.

They free range all day and have access to 300 acres. I don’t know if that was part of your question or not.

If it's just the one hen, then no, I wouldn't treat the whole flock. I'd just address her symptoms as they appear.

Could she have something else going on like reproductive problems or a crop that is not emptying that may be causing some respiratory distress?
