What's wrong with the chicken?

It is a kind of divination for the minorities in southwest China. There are two ways, one is to kill the chicken to get the courage, and see if the courage is broken; Second, take chicken thigh bone, look at the tiny cracks and holes on the bone, insert a bamboo stick (toothpick is also acceptable), and look at the chicken hexagrams in comparison with the pictures, which will break good or bad luck. It is usually seen by wizards or elders. Most people don't know much about this kind of divination, only know.
