Thanks for getting back to me. I have given our hen 2 drops with another reccommended remedy. Will wait and see.Hi, I'm sorry, but I can't remember which hen that was...I wish I'd referred to her by name. I don't remember any of our birds being cured by Oregano Oil, but it is a good thing to have around, and I know some commercial farms use Oregano, as it is a sort of natural antibiotic and very good for gut issues.
