I was given this chicken at a poultry show and I'm trying to nurse her back to a healthy laying girl. She has a voracious appetite; I've been giving her yogurt with applesause & oaks to make sure her belly is right. I add a few drops of applecidar vinegar to her water; given her a bath and blow dry. I've checked her for bugs but can't find any on her. Not sure what else to do.
