Chicken wing bad, chicken head good.

If you maintain a sloppy arm position when your hand is in chamber, with your elbow sticking out sideways rather than being properly tucked straight behind you and your forearm flush with your ribs, you may be accused of having a “chicken wing”. This is bad, but it’s relatively easy to correct with practice.

Ain't no thing but a chicken wing.

More difficult to develop is the habit of keeping one’s head level when performing steps in a given stance, especially lower stances like shiko dachi. The key is to move with the hips and to maintain a straight posture when stepping.

Chicken wings may be an example of how not to chamber your hand, but few animals are as good as chickens when it comes to keeping their heads in a constant position.

So, get rid of those chicken wings in chamber, but try to be like a chicken when you are performing your steps.
