Unity2D - Playing animation with separte body parts/Setting Anchor point to sprites for each frame

Hi there ,

I am having this issue on playing separte animation of chicken for each body parts (head , body and wings), I am not getting an idea on how to plan /architecture such animation .

Creating an animation with in unity2D with different body parts(Like the default example provided by unity 2D) is possible but running animations provided by designers seems to be an issue .

Setting Anchor point to sprites for each frame that could be an option .

Any thoughts ??
