The difference between black-clawed grass chicken and black-clawed hemp chicken lies in:
1. Black-clawed grass chicken has a small head, a small comb, rosy color and long feathers, which can cover the whole body very fully.
2. Black-clawed pheasants are smaller than grass chickens, with compact forequarters, large hindquarters, thin head and feet, short and yellow feet, and tiny black spots on the back feathers of hens.
