If so, any idea how much? Bag says mix .4-.8 oz per pound of food. But she's not eating feed, I have her on an egg/bread/yogurt diet. But if a typical hen eats a pound of food a day, I'm guessing she need to injest .4-.8 oz. per day, mixed in with her special diet. Or is that too much? Never had to deal with a sick hen before. Please help!
