The book on amazon (also on ebay) does look like it has the chicken pattern, but I think it might be a little different though. On the show it was alot of triangles but you might be able to alter this pattern. I saw this yesterday too and remember her referring to her 'chicken on a stick' (which I've been unable to find anywhere!). I know the legs were different, longer, with a knot tied for knees. She showed how to make them, with both sides of the fabric and the batting all sewn at once and then turned right side out with that cool tool. :D
Adorable!
