My chicken I think is slowly dying. I'm not sure how as since she is eating and pooping. But she is very small and bony compared to her sister. I've tried olive oil, massaging, acv, yogurt now baby food. My latest attempt is making her a "crop bra". I'm at my witts end - I don't know what else to do. I'm afraid she is starving. She is acting fine and has color in her comb.
