I'm so sorry for your loss. Know that you were trying to do the best for her. Her short life was much more enjoyable than if she had been born into a chicken factory.
Yes, absolutely. Just be careful that if she flaps when you apply it, it may splatter on you...it doesn't come off easily--need alcohol or nail polish remover to get it off your skin. If you have gloves, wear them when you apply it to avoid staining your hands. I sure hope she recovers!
