The performer takes off his hat when he starts his performance.
Then he shows both sides of a handkerchief to the audience. 
He shows the handkerchief, his hands and his hat is empty, but an egg magically appears in the hat.
He repeats the procedure and another egg shows up.
That is not all... a little walking chick comes from the hat.

A very insteresting and funny trick.
Easy to do, no skill required.
