Start by drawing a circle for the head.
For a chicken, the head is proportionally much smaller than the rest of the body.
A hen is smaller than a rooster and has a shorter neck.
Make two circles for the body.
For a chicken, the circles should be attached with the second circle somewhat above the first.
The body is generally rounder.
Connect the different parts.
Draw the beak, eye, and comb.
For the legs, the joints bend in the opposite direction as human joints.
A hen's tail is smaller than a rooster’s.
To finalize the drawing, trace your sketch with a felt-tip pen.
Don't forget the ridge on the beak.
Since it's a feathered animal, don't worry about having a smooth outline.
Draw the wing over the leg.
A hen's wing feathers run in this direction.
