You need:

-Light gray yarn (head, wings, and upper body)
-Medium gray yarn (lower body and back legs)
-Dark gray yarn (front legs, beak, wing tips)
-Black yarn (hooves, tail)
-White or cream yarn OPTIONAL (for chest and upper-front-legs. It’s sort of a pain to do, but looks nice.)
-plastic safety eyes, or felt to cut out eyes. Or buttons. :]
